Photon-efficient computational imaging with single-photon avalanche diode (SPAD) arrays
Single-photon avalanche diodes (SPADs) are highly sensitive photodetectors that enable LIDAR imaging at extremely low photon flux levels. While conventional image formation methods require hundreds or thousands of photon detections per pixel to suppress noise, a recent computational approach …

RO-Based TDC Design with Configurable Resolution and Power for SPAD-Based TCSPC LiDAR Applications
Single-photon avalanche diodes (SPAD) are used to measure time-of-flight (ToF) using CMOS time-to-digital Converters (TDCs) for compact, low-cost, and highly integrated three-dimensional (3D) sensing. The TDC specifications are critical determinants of the system's range, resolution, and accuracy. …
