Abstract

In an optoelectronic detection device (1) with at least one optical transmitting unit (3) with an electromagnetic pulse generator (4) for emitting electromagnetic emitted pulses (5), and at least one optical receiver for receiving reflected emitted pulses (7) that provides a reception signal, formed depending on the reflected emitted pulse, to an evaluation device (10), wherein the optical receiver (2) is configured to provide a trigger signal (11) for the control of the optical transmitter (3), an improved compensation of the optoelectronic detection device for errors resulting from temperature or ageing should be achieved. This is achieved in that the optical receiver (2) is configured to provide the trigger signal (11) to the evaluation device (10), the optical transmitter (3) is configured to provide a feedback signal (12) to the evaluation unit (10), wherein the feedback signal (12) corresponds to the time point of the transmission of the transmitted electromagnetic pulse (5) by the electromagnetic pulse generator (4), and the evaluation device (10) is configured to determine the time difference between the trigger signal (11) and the feedback signal (12).
