Laser Components USA, a specialized provider of laser and optoelectronic components in the U.S. and Canada, introduced the SPAD2L192, a solid-state complementary metal-oxide semiconductor (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 (630 ft) at a resolution of 4.7 cm (1.9 in). The distance measurement is based on the first-photon, direct time-of-flight principle.

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.
