Abstract
Optical sensing apparatus includes a radiation source, which directs a series of optical pulses toward a target scene. A first array of single-photon detectors receives optical radiation that is reflected from the target scene and outputs electrical pulses in response to incident photons. A second array of counters aggregates and counts the electrical pulses output by the single-photon detectors over respective periods indicated by respective gating signals applied to the counters. Control logic applies the respective gating signals to the counters, in each of a sequence of image frames, so as to cause different ones of the counters to aggregate and count the electrical pulses output by one or more of the single-photon detectors over different, respective gating intervals relative to each of the optical pulses, and to sum the frame histograms generated with different temporal offsets so as to compute and output a cumulative histogram.
