1. An optoelectronic detection device comprising:
at least one optical transmitter with an electromagnetic pulse generator for emitting electromagnetic emitted pulses; and
at least one optical receiver for receiving reflected emitted pulses that provides a reception signal, formed depending on the reflected emitted pulses, to an evaluation device,
wherein the at least one optical receiver is configured to provide a trigger signal for control of the optical transmitter to the evaluation device,
wherein the at least one optical transmitter is configured to provide a feedback signal to the evaluation device, wherein the feedback signal corresponds to a time point of a transmission of the emitted electromagnetic pulse by the electromagnetic pulse generator,
wherein the evaluation device is configured to determine a time difference between the trigger signal and the feedback signal,
wherein the electromagnetic pulse generator is a laser diode,
wherein the optical transmitter is configured to carry out a current measurement of a current through the laser diode, and to provide the feedback signal on a basis of the current measurement,
wherein the evaluation device is a field-programmable gate array in which at least one time-to-digital converter is implemented.
