Beschreibung
Zusammenfassung:	A Light Detection and Ranging (LIDAR) measurement circuit includes an array of single photon detectors configured to detect photons responsive to emission of an optical signal from an emitter, and a pixel processing circuit that is configured to calculate an estimated time of arrival of photons incident on the array of single photon detectors by utilizing a plurality of coarse histogram bins. Respective ones of the plurality of coarse histogram bins are associated with a duration that is greater than one-sixteenth of a pulse width of the optical signal.
