Abstract:
A light receiver (50) is provided having a plurality of avalanche photodiode elements (10) that are each biased by a bias above a breakdown voltage and that are thus operated in a Geiger mode to trigger a Geiger current on light reception, wherein the avalanche photodiode elements (10) have a first connector (20, 22, 28a-b) and a second connector (20, 22, 28a-b); and wherein a first signal tapping circuit (12) for reading out the avalanche photodiode elements is connected to one of the connectors (20, 22, 28a-b). In this respect, a second signal tapping circuit (12) for reading out the avalanche photodiode elements (10) is connected to the other connector (20, 22, 28a-b).
