A LiDAR detection system includes optical sources generating a plurality of output optical signals disposed along a first direction. A modulation circuit applies an output signal from a signal generator to the optical sources to modulate the output optical signals such that the output optical signals are envelope-modulated output optical signals having frequency-modulated modulation envelopes. A scanning device scans the output optical signals into a region over a second direction. A receiver comprising a two-dimensional array of optical detectors receives return optical signals and generates receive signals indicative of the return optical signals. The return optical signals impinge on a mask between the region and the array, the mask comprising a plurality of apertures aligned with a first dimension of the array. The receive signals are generated for a set of detectors in the array disposed along the first dimension of the array and aligned with the mask apertures.
