Abstract

A light receiver (22) having a plurality of avalanche photodiode elements (24) each configured to be biased with a bias voltage above a breakdown voltage and thus to be operated in a Geiger mode for triggering a Geiger current upon light reception, the light receiver (22) comprising a plurality of bias voltage terminals (40a-c) providing different bias voltages, wherein the avalanche photodiode elements (24) form a plurality of groups (421-42n), and wherein the avalanche photodiode elements (24) of a group (421-42n) are each supplied with a same one of the different bias voltages.
