3D Imaging with Geiger-mode Avalanche Photodiodes
Laser radar (ladar) systems enable many points in a scene to be resolved to produce 3D imagery. Researchers at M.I.T.’s Lincoln Laboratory have built such ladar imaging systems using arrays of silicon Geiger-mode avalanche photodiodes—which are capable of detecting as little as a single photon of light —and high-speed, all-digital CMOS timing circuitry in each pixel.
