Paper Abstract

Single-Photon Avalanche Diode (SPAD) sensors are one of the detectors of choice in LIDAR applications, due to their high sensitivity and time resolution. Traditionally, single-point SPAD detectors have been used, necessitating optical scanning, and hence leading to slower acquisition times. However, recent advances in SPAD technology have yielded high pixel count imagers. In these sensors, high sensitivity is ensured by maximising the photo-sensitive area of the device, whilst time-resolved capability is offered by the time stamping of photon detections and/or a programmable timegate synced to the laser source. The resulting sensors show an exciting promise for LIDAR, especially in challenging, low-light, high-speed applications.
