Abstract
A Light Detection and Ranging (LIDAR) receiver includes a receiver optics configured to receive at least one laser beam and direct the at least one laser beam along a receiver path; at least one silicon photomultiplier (SiPM) pixel including an array of single-photon avalanche diode (SPAD) pixels, the at least one SiPM pixel configured to generate at least one electrical signal based on the at least one laser beam; and a spatial filter arranged between the receiver optics and the at least one SiPM pixel, the spatial filter including an aperture located at a focal point of the receiver optics that is configured to permit a passage of the at least one laser beam therethrough and spread the at least one laser beam across the array of SPAD pixels in at least one direction.
