Einrichtung und Verfahren zur Erkennung von Laserstrahlung

The invention relates to a device (1) for detecting laser radiation (45), comprising at least one light inlet (51) and at least one photoelectric transducer (5), which is designed to convert electromagnetic radiation (46) entering through the light inlet (51) into an electrical signal, wherein a modulator (4) is arranged in the beam path between the light inlet (51) and the photoelectric transducer (5), which modulator is designed to modulate laser radiation at a specifiable modulation frequency. The invention further relates to a corresponding method.
