Abstract
A light receiver () having a plurality of avalanche photo diode elements (-) which are biased with a bias voltage greater than a breakthrough voltage and are thus operated in a Geiger mode in order to trigger a Geiger current upon light reception, and having a signal detection circuit () for reading out the avalanche photo diode elements (-), wherein the signal detection circuit () comprises an active coupling element () having an input () connected to the avalanche photo diode elements (-) and an output (), the active coupling element () mapping the Geiger current at the input () to a measuring current corresponding to the Geiger current in its course and level, wherein the input () forms a virtual short-circuit for the Geiger current with respect to a potential (ground, −U; U−U), and the output () is decoupled from the input ().
