1. A LIDAR system for detecting objects within an observation area, comprising:
an illumination unit configured to illuminate the observation area using multiple light radiations, each having a different wavelength and being emitted in the form of light beams, multiple separate spatial areas of the observation area, which are presently covered by a detection area of the LIDAR system, being temporally consecutively illuminated in each case with another of the light radiations; and
a detection unit configured to detect the light radiations reflected by objects in the observation area, including at least one detection array, which is individually assigned to the particular detection area and is made of up of a detector configured to detect the light radiations from the spatial areas presently covered by the detection area and a holographic imaging optics configured to focus the respective light radiations onto the detector, the holographic imaging optics being configured, for each of the light radiations which are focused onto the detector, to focus a particular light radiation of the light radiations from only one spatial area, which is individually assigned to the particular light radiation and presently covered by the detection area, onto the detector.
