Abstract
A LIDAR device for detecting an object in the surroundings, including at least one transmitter for emitting electromagnetic radiation into the surroundings; at least one rotating deflection unit for deflecting the emitted electromagnetic radiation; at least one detection lens system for receiving electromagnetic radiation which has been reflected by the object in the surroundings, and for directing the received electromagnetic radiation at a first detector unit; at least one second detector unit; and at least one diffractive optical element. The at least one diffractive optical element includes at least one first diffraction area and at least one second diffraction area, an at least first diffraction efficiency assigned to the at least first diffraction area being different from an at least second diffraction efficiency assigned to the at least second diffraction area.
