摘要:
A light receiver (100), comprising: a plurality of avalanche photodiode elements (10) each being biased with a bias voltage above a breakdown voltage and thus operated in a Geiger mode in order to trigger a Geiger current upon light reception and a plurality of readout circuits (42, 44, 46) associated with individual avalanche photodiode elements (10) or a group of avalanche photodiode elements (10) for reading out a Geiger current generated upon light reception, wherein the readout circuits (42, 44, 46) each comprise a measurement path (42) and a blanking path (46) as well as a switching element (44) for selectively supplying the Geiger current, or a measurement current corresponding to the Geiger current, to the measurement path (42) or the blanking path (46).
