Abstract
Ladungslawinen-Photodetektor-System, LPS-System, mit einem auf dem Ladungslawinenprinzip beruhenden Ladungslawinen-Photodetektor und einer dem Ladungslawinen-Photodetektor elektrisch nachgeschalteten Verstärkerelektronik, wobei der Ladungslawinen-Photodetektor wahlweise entweder mit einer Vorspannung Vbias oder ohne eine solche Vorspannung Vbias betreibbar ist.

Disclosed is a charge avalanche photodetector system comprising a charge avalanche photodetector based on the charge avalanche effect, e.g. a silicon photomultiplier (1), and an electronic amplifier (2) that is electrically connected downstream of the charge avalanche photodetector, which can be selectively operated with or without a bias. Depending on the bias, the charge avalanche photodetector can be operated in the Geiger mode, in the charge integration mode and as a PIN photodiode. This allows the dynamic range of the detector system to be extended, thereby enabling the detection of both low-intensity and high-intensity optical signals.
