Integrated imager circuit comprising a monolithic array of single photon avalanche diodes

摘要

An integrated imager circuit comprising a monolithic array of single photon avalanche diodes (SPADs) for capturing an image of a scene when said scene is hit by an optical pulse, said array comprising: a plurality of SPADs connected to 2D readout circuits determines the intensity of the light reflected by said scene by counting the number of photons received by said SPADs during a period of time, a plurality of SPADs connected to 3D readout circuits determines the distance to said scene by determining the elapsed time between the emission of each pulse and reception of the corresponding reflected photons.
