Abstract
A receiver unit includes at least one single photon avalanche detector element of a Geiger mode and a time-to-digital converter circuit. Each single photon avalanche detector element is enabled to detect a photon in at least one time-gated window, and each single photon avalanche detector element is configured to output an electric pulse in response to detection of a photon of optical radiation within the at least one time-gated window. The time-to-digital converter circuit provides timing data associated with said electric pulse for determination of a distance of a target on the basis of the timing data provided by the time-to-digital converter circuit.
