1. PREAMBLE – VORWORT Dear friends of the Lab MST, We report with this small booklet about our activities in lecturing, innovation, scholarship and research of the laboratory of measurement and sensor system technique (MST). This year we celebrate the twelfth anniversary. It is a good occasion for looking back and forward. We have created several statistical diagrams that deliver an insight to the development of the Lab MST. In 2016, a variety of activities has been carried out successfully. We are funded from nine projects of the DFG (German Research Foundation) and several projects of other funding organizations and by industry. We hope to be supported in the future by projects in the field of biomedicine. In the engineering sciences, a strong contact with the industry has to be maintained. In this sense, the successful cooperation especially with the companies Deutsche Solar AG (Solar-World AG), ILA GmbH, Optolution GmbH, Infineon Technologies AG, SeeReal Technologies GmbH, and Sick AG have to be emphasized. An obligation of research projects is a publication activity with high recognition. In this year, over 50 talks and publications have been conducted, including over 10 papers in high quality peer-reviewed SCI-journals. One of our papers has been published in the Journal of Power Sources, which has an Impact Factor of 6.2. A further highlight to draw attention is the six-time publication in the OSA journal Optics Express, which has a high reputation in its scien-tific field: “Ranked #1 in Optics by Eigenfactor (0.2499), Ranked #2 in Optics by Total Cita-tions (81,379), Ranked #2 in Google Scholar Optics & Photonics Category (h5-index 105)”. Within the last 12 years, over 500 talks and publications, including 15 patents and over 100 journal papers have been conducted. Several students have made a highly valuable contri-bution to these achievements. Students have co-authored international journal papers and presented their research at international conferences. This year, the students of the Lab MST have applied for a Student Chapter of SPIE (the international society for optics and photonics). Nine scientific prizes were awarded to the members of the Lab MST in 2016. Congratulations to the award winners. A very success story is the appointment of Prof. Dr.-Ing. habil. Andreas Fischer as Full Professor at University of Bremen. Since August 2016, he is head of the Bre-men Institute for Metrology, Automation and Quality Science (BIMAQ). The Lab MST conducts a Reinhart Koselleck project (RKP) of the DFG to strengthen funda-mental research since 2014. The RKP program enables to pursue exceptionally innovative, higher-risk projects. Within just two years, five high-impact SCI-journal papers have been published and a huge number of invited talks at renowned conferences. A movie titled “Transmission of Multiple Signals through an Optical Fiber using Wavefront Shaping” on the results of the RKP will be provided by the Journal of Visualized Experiments (JoVE). Besides outstanding results in adaptive flow metrology, new high-risk research fields have been con-

5

quered. Exploiting the scattering processes in fibers with modern wavefront shaping tech-niques enables novel approaches for optogenetics, stem cell research, contactless mechan-ical phenotyping of cells and tissue as well as cryptography with physical layer security. With this interdisciplinary approach of the RKP, internationally renowned research at the inter-face between electrical and computer engineering, physics, biology, medicine, and mechan-ical engineering have been conducted, which goes successfully far beyond the scope of typ-ical DFG-funded projects. Adaptive optics is of interest for Light Sheet Microscopy, Confocal Microscopy, Wide-field Fluorescence Microscopy, and Structured Illumination Microscopy. We have realized an adaptive HiLo 3D-microscope using structured illumination, which can be applied to identify thyroid gland disruptors in transgenetic Zebrafish embryos. To handle genetically modified organisms we have established a level 1 genetic laboratory (S1 Lab).

This year, the proposal of the COST Action CA16124 “BioBrillouin - Brillouin Light Scattering Microspec-troscopy for Biological and Biomedical Research and Applications” has been accepted by EU. Since Bio-Brillouin is still in its infancy, major challenges in the development of novel instruments and important applications in biomedicine can be envisaged. We are looking forward to network-ing with BioBrillouin over the next 48 months.

Due to the steadily increasing number of employees and students, we have a constant de-mand for new rooms. This year, we were happy to put a new fully equipped optic laboratory (BAR 062) into operation providing experimental space of three optical tables. However, due to the construction work, e.g. pneumatic hammer and dredging tasks directly in front of the offices, delays occurred during the project work. We aim to combine fundamental research, project work, innovations, learning and teaching. Results of research and development projects foster high quality teaching and vice versa. This year, about 900 examinations were accomplished by the Lab MST! Recently, we have organized the conference of GALA e.V. In 2017, we are happy to host the conference of DGaO (German Society of Applied Optics).

Finally, I would like to thank all students and employees of the Lab MST for their dedicated work on research and teaching at the TU Dresden.

Best regards,

Prof. Jürgen Czarske

7. RESEARCH PROJECTS (SELECTION) – FORSCHUNGSPROJEKTE

DFG Ultrasound instrumentation with adaptive beam shape for investigating

turbulent liquid metal flows Staff: Dipl.-Ing. R. Nauber, Dipl.-Ing. K. Mäder, Dr. L. Büttner, Prof. J. Czarske Aim: Investigating magnetically influenced flows in liquid metals and semiconductors is

increasingly important for optimizing industrial processes as steel casting and pho-tovoltaic silicon production. Especially the characterization of turbulent flows is highly relevant in that context. Turbulent flow behavior can be described by two-point correlation functions, which are determined by measuring the velocity at two locations at the same time with a high spatial resolution for varying the distances of those two points. At the moment no available flow instrumentation for liquid met-als provides this measurement modality. Our research project approaches the measurement task by using an ultrasound phased array for providing two independent steerable and focusable sound beams. This allows a simultaneous velocity measurement at two different locations with high spatial resolution and enables the measurement of turbulence characteristics in liquid metal flows. A validation of the measurement system is performed on a well-known channel flow. The experimental application to magnetically influenced channel flows and to submerged nozzle flows is planned. By providing means of tur-bulence characterization it, is desired to aid optimizing the material properties of metals and semiconductors through application of custom-tailored magnetic fields.

DFG Investigation of the Interaction between Blade Tip Flow and Blade Vibrations in highly loaded axial compressors

Staff: Dipl.-Phys. R. Schlüßler, Dr. L. Büttner, Prof. J. Czarske Aim: In turbomachinery, gap flow effects at the blade tips lead to large losses and stabil-

ity impairments, especially for highly loaded compressor stages. The scientific inves-tigation of these phenomena is very difficult because both the numerical and exper-imental methods for studying the flow reach their limits due to the complex pro-cesses in the gap. In addition, interactions occur between aerodynamic and struc-tural-mechanical effects that could be studied and modelled only rudimentary up to now. Within this proposed project, simultaneous high-precision measurements of both the blade tip flow profile and the compressor blade vibration amplitudes and mode shapes will be enabled employing novel laser-based measurement methods. There-with, the mechanisms of interaction between gap flow and blade vibrations will be investigated experimentally at a transonic compressor test rig alongside with nu-merical simulations in order to gain a better, fundamental understanding of the aeroelastic processes in turbomachinery, especially in highly loaded compressor stages. The results would be very valuable for turbo machine design, e.g. for being able to reduce the blade row spacing in future. Accordingly, higher power density and im-proved rotor dynamics can be achieved. This would directly allow for an increase in both operating reliability and flexibility of load changes. Furthermore the energy ef-ficiency of future turbo machines, such as aircraft engines, could be improved.

DFG Laser optical measurements of the acoustic particle velocity at bias flow liners with grazing flow

Staff: Dr. D. Haufe, Dipl.-Ing. J. Gürtler, Prof. J. Czarske Aim: For a stable and low-noise operation of a modern jet engine, especially in case of

lean combustion, highly efficient sound attenuators with bias flow (bias flow liners) are needed, since the combustion chamber of such an engine tends to suffer from combustion oscillations, but little air mass flow is available for the damping. How-ever, the optimization of the damping efficiency of these bias flow liners requires a deeper understanding of the physical damping mechanisms. The damping perfor-mance of such a liner is determined by complex phenomena of interaction between the incident sound field and the flow field. Therefore, the goal of the research pro-ject is to reach a better understanding of these phenomena. To this end, an energy balance of the transfer from the sound field to the flow field is aspired. On the one hand, this necessitates three-dimensional measurements of the acoustic particle velocity and the flow velocity field. To achieve this, the Doppler global velocimetry with sinusoidal laser frequency modulation (FM-DGV) will be applied, which has been proven suitable already during the first funding period. On the other hand, the challenge concerning the evaluation of the velocity fields measured above the bias flow liner is to separate the acoustically induced hydrodynamic oscillations from the primary sound and flow field. For this purpose, different analysis and separation methods have to be tested and to be applied. Finally, the qualified measurement techniques and analysis methodology are applied at a simplified bias flow liner. The established transfer will be proven by a comparison with the sound energy dissipa-tion of the liner obtained by microphone measurements. The investigation enables gaining new insights concerning the physical damping mechanisms at bias flow lin-ers. The funding of the cooperation project by DFG (grant no. CZ 55/25-3 and EN 797/2-3) is gratefully acknowledged.

DFG Novel three dimensional shape measurement technique for fast rotating objects Staff: Dipl.-Ing. R. Kuschmierz, Prof. J. Czarske Aim: The objective is to investigate a three dimensional shape measurement technique.

It is important to capture the shape of fast rotating objects at different process techniques for instance to control the production process in metal working lathes. The state of the art is to unclamp the workpiece, to measure the shape by tactile techniques and to clamp it again into the lathe. However, clamping tolerances re-sult. We propose to use one optical sensor to measure the shape inside of the ma-chine. This novel sensor, a phase evaluating laser Doppler distance sensor (P-LDDS), measures simultaneously the lateral velocity and the distance of moving objects. The distance is measured by the evaluation of the phase difference of two tilted in-terference fringe systems. Generally high tilting angles allow small distance meas-urement uncertainties of the P-LDDS. However, during preliminary experiments a reduction of the correlation coefficient between the measurement signals at in-creased tilting angles has been recognized. It is caused by the speckle effect and re-sults in an enhanced distance measurement uncertainty. Within the preliminary ex-aminations a scientific breakthrough has been achieved. By matching of the illumi-nation and detection optics the correlation coefficient has been significantly im-proved. At isotropic rough surfaces a distance measurement uncertainty in the sub-micrometer range has been achieved already. However, the optical and signal pro-cessing technique has to be analyzed at real technical surfaces. Within the project fundamental investigations on the measurement uncertainty budget are performed. Anisotropic roughness, waviness, grooves, rills and macroscopic curvatures of typi-cal technical surfaces are studied in order to learn how to improve the optical and signal processing system. Three dimensional shape measurements with submicron uncertainty are achieved in metal working lathe in cooperation with the PTB.

DFG Adaptive laser systems with wave front correction and phase conjugation for fluid flow measurements for refractive index effects

Staff: Dipl.-Ing. H. Radner, Dr. N. Koukourakis, Dr. D. Haufe,

Dr. M. Teich, Dr. L. Büttner, Prof. J. Czarske Aim: The aim of the Reinhart Koselleck project is for the first time the systematic investi-

gation of fundamentally new adaptive measurement techniques for fluid flows. In the case of light propagation through transparent media with refractive index gradi-ent fields caused by temperature, pressure or concentration variation as well as dy-namic phase boundaries, wave front distortion appear that lead to not tolerable measurement uncertainties. In order to correct these distortions, adaptive meas-urement systems for fluid flow shall be investigated by using modern feedback con-trol methods and optomechatronic components. The adaptive measurement tech-nique enables for the first time the turbulence investigation of film and jet flows with free, dynamic surfaces. It is aimed to give a contribution to the improvement of the energy efficiency of procedural sites. Furthermore it is planned to perform digital optical phase conjugation in order to measure flows in strongly scattering, non-transparent media. The digital optical phase conjugation reduces the optical aberration which results in a larger penetration depth into the scattering medium. Blood flows in deep, strongly scattering tissue and sediment layers shall be meas-ured in order to investigate arteriosclerosis. The vision is gathering knowledge about currently not measureable flows in biomedicine and contributing to the treat-ment of cardiovascular diseases.

DFG Flow investigations in liquid metals for crystal growth under the influence of a travelling magnetic field using a dual-plane ultrasound measure-ment system

Staff: Dipl.-Ing. N. Thieme, Prof. J. Czarske Aim: The objective of the research project is a detailed investigation of complex flows oc-

curring at the directed solidification of metal melts using the vertical gradient freeze method with a travelling magnetic field. For growing semiconductor crystals from a melt, the crystal quality can be improved by applying spatially and temporally tai-lored magnetic fields during the growth process. The occurring flow fields are char-acterized by complex three-dimensional and time-varying structures. The flow measurements have to be performed simultaneously in at least two planes. Up to now, such investigations failed because of the insufficient properties of measure-ment techniques applicable to liquid metals. To overcome this problem, a novel multi-component dual-plane ultrasound measurement system will be employed which uses ultrasound-arrays driven in a combined time and frequency division mul-tiplexing operation. Due to the progress in available computing power the flow pat-terns and the temporal evolution from one to another can be recorded and studied in real-time and especially for long measurement time intervals. In this project, imaging investigations of the melt flow in two planes under thermal, geometric and magnetic conditions relevant for crystal growth will be accomplished for the first time. The investigation of transient and fluctuating flow situations in de-pendence of the melt height takes centre stage. From the fluid mechanical point of view a special interest lies in the point how the transition between two-dimensional and three-dimensional as well as between stationary and time-varying flow patterns takes place. The results gained by experiment will continuously be compared with those of numeric simulation. This benefits not only the development of the model configurations but also the verification of numeric models for flow simulation. The results will be transferred to real crystal growth processes by means of scaling laws which will be developed during the project. They also will be the basis for the devel-opment of future strategies for flow control using magnetic fields

DFG Aberration correction for real-time measurements in adaptive confocal microscope

Staff: M. Sc. K. Philipp, Dr. N. Koukourakis, Prof. J. Czarske Aim: Microscopic techniques with high spatial and temporal resolution are required for

measuring biological cells and tissues. Confocal microscopy is an established tech-nique, which is based on a pinhole detection that introduces optical sectioning abili-ties. The usage of microscope objectives with high numerical aperture allows achieving high spatial resolution, but simultaneously increases the impact of sys-tematic aberrations. These aberrations add to sample induced aberrations and limit the achievable resolution of a confocal microscope. Aberrations can be addressed by using adaptive optical elements. Furthermore adaptive elements allow for fast scanning. In the preparatory work we successfully verified, that two adaptive lenses, one in the illumination and the second in the detection path, allow for the first time, to create axial scans with homogeneous axial resolution over the whole depth-range. The aim of the proposal is to create a fully-adaptive confocal microscope, which enables both fast scanning and high spatial resolution due to aberration cor-rection. For this purpose novel adaptive lenses with integrated aberration correc-tion will be developed and used to create the axial scanning. These lenses enable to compensate for both symmetric (spherical, defocus) und asymmetric (astigmatism, coma)-aberrations our confocal microscope. Integrated pressure sensors allow con-trolling the focal length of the adaptive lens. For lateral scanning adaptive prisms are used, which promise to create fast lateral scans with less aberrations and com-pact setup. Using the novel adaptive devices opens up the possibility to miniaturize the confocal setup and to create a compact and hand-held microscope. As a first test paradigm, the new confocal microscope will be used to identify thyroid gland disruptors in Zebrafish embryos.

DFG Full-Field Laser Vibrometry for Combustion Diagnostics Staff: Dipl.-Ing. A. Ramos, Dipl.-Ing. J. Gürtler, Dr. D. Haufe, Prof. J. Czarske Aim: State-of-the art technology in industrial gas turbines for power generation uses lean

premixed combustion for high combustion efficiency and low emissions. High power densities and lean combustion increase the susceptibility to thermoacoustic oscilla-tions. Modelling and prediction of instabilities is often accomplished by analysing the flame transfer function (FTF), which relates the unsteady heat release rate from the flame to perturbations of incoming velocity as function of frequency. Such char-acterization of flames is also necessary for turbomachinery in aero-engines. Since research in the field of turbomachinery always is energy related research, a strong impact on society is given. In previous projects of TU Graz (J. Woisetschläger) funded by the Austrian Science Fund FWF it was shown that so-called laser-vibrom-eters – interferometers used in engineering for surface vibration detection - can di-rectly record density and heat release fluctuations. It also turned out that two laser vibrometers can detect flow velocities in flames by correlating density fluctuations. Heat release and velocity are both needed for FTF recordings. Inspired by modula-tion and demodulation techniques from communications engineering, proofed the concept of another laser-optical measurement using sinusoidal laser frequency modulation technique - also inherent to laser vibrometer technology - in combina-tion with modern highspeed sensor arrays and spatio-temporal correlation tech-niques for fluid flow investigations. The hypothesis of this project is that laser vi-brometer technology can be combined with modern high-speed camera sensors, so that such a proposed full-field interferometry based on numerous laser vibrometers (each pixel one vibrometer) can record FTF, and also provides field information on heat release rate and velocity as well as spatio-temporal correlations within the flame – all without the need for tracer particles or tracers and all novel to combus-tion diagnostics. In this project the expertise of both TU Graz and TU Dresden will be combined to verify this hypothesis and develop a full-field laser vibrometer for la-seroptical high-speed combustion diagnostics, starting from the thermo-acoustics needed to characterize the flame, including appropriate spatial/temporal correla-tions for single and dual directional observations. This project includes a bench-marking with single line-of-sight laservibrometers (TU Graz) and high-speed velocity recordings (TU Dresden).

DFG Monochromatic flow profile sensor with time division multiplexing and calibration models for fluids

Staff: Dipl.-Ing. M. Bermuske, Dr. L. Büttner, Prof. J. Czarske Aim: The aim of highly spatially resolved flow profile measurements even at large working

distances can be achieved by means of the laser Doppler velocity profile sensor, whose properties have been investigated within a research project funded by Ger-man Research Foundation. The sensor is based on the utilization of two superposed interference fringe systems distorted by defined wavefront curvature. Using a two-channel measurement, which so far has been generated by means of two laser wave-lengths, the position of particles carried with the flow can be determined with mi-crometer spatial resolution. Measurements in the proximity of walls can be per-formed using fluorescent scattering particles, however, a sensor employing only one laser wavelength is necessary to this end. Hence, a monochromatic profile sensor based on time division multiplexing is to be investigated and realized until a demon-strator within this transfer project.

Beside measurements in wall proximity, one key aspect of this project will be the development of a model for sensor calibration. Since the geometries of the interfer-ence fringe systems depends on the refractive index of the surrounding medium, any change of the working fluid would demand a new calibration. Especially in liquids, a calibration based on rotating velocity references is impractical, so that a deep pene-tration of the market cannot be expected. This problem will be solved by developing a calibration model.

AiF Realization of a LDV Profile Sensor Measurement System Staff: Dipl.-Ing. M. Bermuske, Dr. L. Büttner, Prof. J. Czarske Aim: The limited spatial resolution of conventional LDV-systems is increasingly problem-

atic for a variety of applications such as Investigation of boundary layer flow, near surface turbulence and vortex development and flow rate measurements in tubes. The available alternative measurement techniques like pitot tubes and hot-wire an-emometers are not contactless, they complicate the access to the measurement lo-cation and they require complex calibration. Motivated through this problems at the PTB Braunschweig and at the TU Dresden fundamental research is applied to additionally obtain the longitudinal position of a particle that travels through the measurement volume of a LDV. With these techniques it is possible to correlate the position (in the µm-regime) to the velocity inside of the measurement volume. Based on this works, two industrial sensors (incl. signal processing, calibration con-cept, uncertainty budget and extensive testing and characterization) shall be devel-oped – on the one hand for the retrofitting of a conventional LDV-system, on the other hand as a complete stand-alone multifunctional measurement system.

AiF Ultrasound and simulation for highly laden particle suspensions on the example of Zn-Slurry batteries

Staff: Dipl.-Ing. C. Kupsch, Prof. J. Czarske Aim: Highly laden particle suspensions appear in many technical processes, e.g. as elec-

trolyte in redox flow batteries or as raw materials as well as products in the food in-dustry. Knowledge of the complex multiphase flow phenomena raises possibilities of optimization and increased efficiency of these technical processes. In this research project new simulation tools for the investigation of flows of highly laden particle suspensions will be developed by the fuel cell research center ZBT in Duisburg. At the same time a new ultrasound measurement system for the investi-gation of complex multiphase flow fields in small geometries is designed at the chair of measurement and sensor system techniques. On the basis of simulations and measurements of the flow field inside a working zinc-slurry battery the new simula-tions tools are validated with experimental data. Due to the high specific energy content, the high availability and low cost of the materials and the recyclability, zinc-batteries have enormous potential as scalable and economic energy storage systems. The challenge of measuring flow fields in highly laden particle suspensions is the strong scattering effect of the suspended particles. On the one hand this results in a strong attenuation of the ultrasound wave. On the other hand parasitic multiple re-flections superimpose the actual measurement signal reflected by particles in the target measurement region. To overcome these difficulties the phased array princi-ple and a specific ultrasound frequency depending on the particle size distribution is used, which first of all results in a reduced influence of multiple reflections and at-tenuation and secondly allows measurements in small geometries.

AiF Development of a flow-optimized HT-PEM fuel cell stack using a novel high-resolu-tion flow sensor and efficient simulation schemes

Staff: Dipl.-Phys. F. Schmieder, Dr. L. Büttner, Prof. J. Czarske Aim: Due to positive specifications like slow degradation, higher efficiency and better

handling, high-temperature polymer electrolyte membrane (HT-PEM) fuel cells are especially suited for end-user applications and are already established in many are-as as back-up systems, remote power supply or combined heat-and-power systems. The coupling of several fuel cells for higher voltages still poses a challenge, as it in-troduces flow distribution inequalities which lead to significantly lower overall effi-ciency. Compensating this inequality is a complicated task, as the state of the flow is generally unknown and hard to measure due to the confined spaces. Based on a previous cooperation (project 407 ZBG), this project will address several aspects of HT-PEM fuel cell stacks.

In this project, we will develop a novel flow sensor based on the Laser Doppler Flow Profile Sensor which will use a fast time-division multiplexing technique to enable the investigation of near-wall flows in confined spaces < 1 mm using fluorescing par-ticles with high spatial resolution. Furthermore, sophisticated simulation schemes will be developed, which will encorporate important physical aspects of fuel cell ac-tivities like transport of warmth, electrochemical reactions and mass transport as a reduced model to enable the simulation of whole fuel cell stacks, which is impossi-ble as multiphysics simulation to date and will greatly facilitate the a-priori develop-ment of HT-PEM systems. Validation and calibration of these simulations will be done using the novel flow sensor. The project will lead to more efficient HT-PEM-fuel cell systems and will furthermore enable time-efficient pre-production investi-gation of such systems. A high-resolution flow sensor for near-wall measurements will be another independent result of this project.

BMU Ultrasonic measurement techniques for model experiments of the directional so-lidification

Staff: Dipl.-Ing. N. Thieme, Dr. L. Büttner, Prof. J. Czarske Aim: During the production of polycrystalline silicon ingots for photovoltaics the melt

flow is of great importance. The melt flow affects both the shape of the solidifica-tion front as well as the transport of impurities. By the well-directed application of time-dependent magnetic fields the flow characteristics can be optimized. An important prerequisite for the optimization of the melt flow is a comprehensive understanding of the forces that influence the melt flow. In the ENOWA joint pro-ject this understanding is to be obtained by the comparison of numerical simula-tions and experimental investigations on a model experiment. These works form a key aspect for the overall objective of the project in which in-creasing the efficiency of solar cells and improving the process yield by enhancing the crystallization technology.

Ph.D. Thesis: Dr.-Ing. Raimund Schlüßler "Optisches Geschwindigkeitsmesssys-tem zur vektoriellen Erfassung instati-onärer Strömungsprozesse " Abstract: The reduction of the consumption of resources and the noise and polluting emissions of technical flow processes such as combustion and injection pro-cesses is of high social relevance and requires a deeper understanding of the occurring flow phe-nomena. For this purpose the metrological acquisition of the flows is necessary, whereat especially the flow velocity is of high interest. However, flow velocity measurements in dynamic or reactive fluids make great demands on the engaged measurement techniques. In order to resolve velocity oscillations or unsteady phenomena with short timescales a simultaneous three component meas-urement with a high measurement rate of 100 kHz or more is required. To analyze complex and small-scale velocity fields an imaging or volumetric measurement with a high spatial resolution is desired. Currently available measurement systems do not fulfill all these requirements. Hence, the goal of this work is the development, characterization and qualification of a measurement system suitable for the temporally resolved acquisition of unsteady flow processes in highly dynamic and reactive fluids.

Ph.D. Thesis: Dr.-Ing. Ullrich Doll “Gefilterte Rayleigh-Streuung zur simultanen Bestimmung von Druck-, Temperatur- und Geschwindigkeitsfeldern in Gasströmungen“ Abstract: The characterization of gas flows is of great importance both in aero-space as well as power engineering. Laser-optical methods are capable of spatially and temporally resolved measurements with minimal influence on the investigated phe-nomenon. The aim of this work is to provide a measuring system based on spectrally filtered Ray-leigh scattering (FRS), which allows for a simultaneous determination of time-averaged pressure, temperature and velocity fields under the challenging conditions of modern gas turbine test benches. The FRS technique utilizes the absorption bands of atomic or molecular gases to filter laser stray light from surfaces or large particles from the measured signal. Previous implementations of the technique are based on pulsed laser light sources. Despite their general usability under test rig con-ditions has to be discussed, many of these systems suffer from spectral broadening mechanisms which lead to an insufficient suppression of laser stray light. In contrast, the employed solid-state continuous-wave laser of this contribution benefits from its high spectral quality as well as robust and compact design.

Tagungsort 2017: Dresden – Stadt der Wissenschaft

Als Sitz der Sächsischen Staatsregierung und des Sächsischen Landtags ist Dresden das politische Zentrum des Landes. Dresden - liebevoll Elb� orenz genannt - bietet Sehenswertes in vielerlei Gestalt: Dresdner Zwinger, Frauenkirche, Semperoper und Residenzschloss prägen wie viele weitere historische Baudenkmale und Ensemble das Bild der Stadt. Das deutsche Hygiene-Museum, die Sächsische Schweiz und das Barockschloss Moritzburg, aber auch die Juwelen der kurfürstlichen Schatzkammer und Ra� aels Sixtinische Madonna sind weitere Highlights. Mit ungefähr 110 Geburten pro 10.000 Einwohner ist Dresden eine der geburten-reichsten Städte Deutschlands.

In Dresden verschmelzen Wirtschaft, Wissenschaft und Forschung. Ein exzellenter Standort, herausragend in den Feldern Mikroelektronik, Nanotechnologie, Neue Werksto� e, ange-wandter Optik, Biomedizin und Biotechnologie. Mit etwa 40.000 Beschäftigten ist das Silicon Saxony der größte Mikroelektronikstandort Europas. Leuchttürme wie die TU Dresden, Max-

Planck-, Leibniz-, Helmholtz-, und die Fraunhofer-Institute locken Wissenschaftler aus der ganzen Welt an. Gemeinschaftsprojekte wie DRESDEN-concept, eine Kooperation zwischen Technischer Universität sowie außeruniversitären Forschungs- und Kultureinrichtungen bündeln die Kompetenzen in den Bereichen Forschung, Ausbildung, Infrastruktur und Verwaltung. Seit der dritten Runde der Exzellenzinitiative werden an der TU Dresden zwei Exzellenzcluster und ein Graduiertenkolleg gefördert. Außerdem gewann die TU Dresden das Zukunftskonzept „Synergetische Universität“. Die angewandte Optik stellt einen Schwerpunkt der Forschung in Dresden dar. Zu nennen sind die Biophotonik, organische Leuchtdioden, smarte Mikroskopie, Hochleistungslaser für Krebsbehandlungen, optische Nachrichtentechnik, Lasermaterialbearbeitung, optische Systeme für die Mikro- und Nanoelektronik, Mikrosystem- und Nanotechnologie, digitale Lasersysteme und die optische Messtechnik.

Wir sind uns sicher, dass die 118. Tagung der DGaO in Dresden/Elb� orenz hervorragende Möglichkeiten zum wissenschaftlichen Austausch bieten wird, und freuen uns darauf, Sie im nächsten Jahr bei uns begrüßen zu dürfen.Prof. Jürgen Czarske, Tagungsgeschäftsführer
