Abstract
A receiving unit, in particular for a LIDAR device, for receiving rays reflected and/or backscattered from an object. The receiving unit includes receiving optics and at least one detector, wherein arranged in a ray path of the rays between the receiving optics and the detector are a directional filter and a wavelength-selective unit. A LIDAR device and a method for evaluating measurement data of a detector are described.

1-13. (canceled)
A receiving unit for a LIDAR device for receiving rays reflected and/or backscattered from a sampling region, the receiving unit comprising:
- receiving optics;
- at least one detector;
- and
- a directional filter and a wavelength-selective unit arranged in a ray path of the rays between the receiving optics and the detector.
A LIDAR device for sampling of sampling regions, comprising:
- at least one transmitting unit configured to generate and radiate generated rays into a sampling region;
- and
- at least one receiving unit for receiving rays reflected and/or backscattered from the sampling region, the receiving unit including:
- receiving optics,
- at least one detector, and
- a directional filter and a wavelength-selective unit arranged in a ray path of the rays between the receiving optics and the detector.
A method for evaluating measurement data of a detector of a receiving unit, the method comprising the following steps:
- receiving, by the receiving unit, rays from a sampling region;
- filtering, by a directional filter of the receiving unit, the receiving rays, the filtered rays being guided directly or via at least one first optical element, onto a wavelength-selective unit;
- splitting up, by the wavelength-selective unit, the filtered rays wavelength-dependently and radiating them wavelength-dependently onto different light-sensitive regions of the detector.
