Abstract
A light receiver () is provided having a plurality of avalanche photodiode elements () that can each be biased above a breakdown voltage by a bias voltage and can thus be operated in a Geiger mode, wherein the avalanche photodiode elements () form a plurality of groups, and having a control unit () to change the sensitivity of the avalanche photodiode elements () of a respective group. In this respect, the control unit () is configured to respectively change the sensitivity of the avalanche photodiode elements () of a group at at least one point in time assigned to the group, with different points in time being assigned to the groups.
