Abstract
A light pulse detection circuit for connection to a photodiode, the detection circuit comprising an integration capacitor, discharge means, and comparator means adapted to compare an integration voltage across the terminals of the integration capacitor with a reference voltage threshold in order to produce a light pulse detection signal. The reference voltage threshold is a self-adaptive threshold depending on a level of light background noise. A detection device comprising a photodiode and such a detection circuit. A detection matrix comprising a plurality of such detection devices.
