Abstract: Depth sensing apparatus (20) includes a radiation source (21), which is configured to emit a first plurality of beams (30) of light pulses toward a target scene (32). An array (24) of a second plurality of sensing elements (78) is configured to output signals indicative of respective times of incidence of photons on the sensing element, wherein the second plurality exceeds the first plurality. Light collection optics (34) are configured to image the target scene onto the array of sensing elements. Processing and control circuitry (26, 28, 35) is coupled to receive the signals from the array and is configured to search over the sensing elements in order to identify, responsively to the signals, respective regions of the array on which the light pulses reflected from the target scene are incident, and to process the signals from the identified regions in order determine respective times of arrival of the light pulses.
