Unified photodetector and electrode array

A photodetector is made sufficiently large to receive an entire designed field of view (e.g., for a LiDAR system). At least one lens is mounted to direct reflected laser beams to the photodetector. A plurality of electrodes (e.g., 16, 32 or 64) are coupled to the photodetector, each electrode corresponding to a different pixel position. A processor is coupled to the plurality of electrodes and the processor is configured to detect a pixel position of a reflected laser beam by detecting which electrode produces the largest digital signal.
