>250m Ranging

•Low reflective 5% target

•Bright sunlight operation

•Excellent resolution

Compact systems which blend into the vehicle

•Very small apertures possible

•Solid state designs

Lowest cost

•Trend is for more and more IC integration and standard products

•NIR/9xxnm will always be 10x cheaper than SW NIR/1550nm

Modeled performance improvement

of SiPM sensor vs. APD

Detector is a critical component to achieve distance

• IATF 16949

• AEC Q102

• -40-1050C operation

• Tight uniformity of voltage and gain across millions of sensors

•Required for ease of system calibration and lower mfg. cost

•SiPMs have 10,000 more gain than APD and 1Mx more than PIN Diode

•Cross talk of <20% will provide excellent SNR

•15% today is best in class for NIR. Expect doubling in next 18 months

•NIR will be the predominate wavelength due to 10x lower cost and large ecosystem

Examples of SiPM

and SPAD sensors

为什么 SPAD Arrays 更好？

Improved angular resolution

• Higher density pixels = higher resolution & more point cloud details

Better ambient light rejection

• <5ns recovery time = less dead time

Flexibility for low cost system design

• Flash for short range

• Scanning for long range

Rx:

Pandion chip and staring optic

Allow for wide field rolling shutter readout eliminating scanning for long distance if desired

Wide range of markets from automotive to consumer
