Silicon single photon avalanche diodes detector arrays for underwater applications

Time-correlated single-photon counting (TCSPC) has been established as the preferred detection approach for high performance lidar and depth profiling due to its excellent surface to surface resolution and high optical sensitivity. This presentation will show the results of laboratory-based experiments obtained using different optical transceiver configurations. Particular attention will be given to underwater depth imaging using silicon single photon avalanche diode (Si-SPAD) detector arrays fabricated in complementary metal-oxide semiconductor (CMOS) and Si SPAD detector arrays built in custom fabrication technology.
