Abstract
Optical sensing apparatus includes at least one semiconductor substrate and a first array of single-photon detectors, which are disposed on the at least one semiconductor substrate, and second array of counters, which are disposed on the at least one semiconductor substrate and are configured to count electrical pulses output by the single-photon detectors. Routing and aggregation logic is configured, in response to a control signal, to connect the single-photon detectors to the counters in a first mode in which each of at least some of the counters aggregates and counts the electrical pulses output by a respective first group of one or more of the single-photon detectors, and in a second mode in which each of the at least some of the counters aggregates and counts the electrical pulses output by a respective second group of two or more of the single-photon detectors.
