LIDAR SYSTEM HAVING A RAY OPTICS DIAGNOSIS

A LiDAR system including an emitter and a detector, as well as a ray optics that is at least developed to deflect a ray of light emitted by the emitter for scanning an environment in a normal operation. The LiDAR system has a diagnosis system situated in the LiDAR system. In a diagnosis operation, the ray optics is configured to deflect the ray of light from the emitter onto the diagnosis system and to guide the light reflected by the diagnosis system to the detector in order to detect a diagnosis light signal. A control unit of the LiDAR system is developed to detect an error in the ray optics based on a difference between an expected diagnosis light signal and the actually received diagnosis light signal.
