SPAD Arrays for Flash LiDAR

Highly-sensitive CMOS Sensors

With the SPAD2L192, LASER COMPONENTS now also offers a solid-state CMOS sensor for Flash LiDAR applications..

With a resolution of 192 x 2 pixels, the single photon
avalanche diode (SPAD) array offers very high sensitivity and high temporal resolution. The
noise is below 50 cps. The in-pixel time-to-digital converter, which features a temporal resolution
of 312.5 ps and a scale value of 1.28 μs, enables a nominal range of up to 192 m
at a resolution of 4.7 cm. The distance measurement is based on the first-photon, direct ToF
The arrays in Flash LiDAR applications do not capture just one point like they do in classic
LiDAR. Each individual pixel provides position information. In the SPAD array presented
here, the sensor and evaluation electronics have been mounted on the same chip for the first
time, thus the array takes up very little space.
