Abstract
A LIDAR device is described including a beam source for emitting electromagnetic radiation in an emission path, in which at least one holographic optical element is situated for diffracting the emitted electromagnetic radiation, and a detector for detecting incident electromagnetic radiation in a reception path, an optical bandpass filter being connected upstream from the detector. Depending on a wavelength of the emitted electromagnetic radiation, the holographic optical element effectuates a diffraction by at least one angle of reflection which is matched to the shift of the wavelength of the incident electromagnetic radiation with the aid of the bandpass filter.
