Abstract: A light detection and ranging system is disclosed. The system includes a first light source for sending a light signal and a photo detector for receiving a light signal from the surroundings of the system. A signal processing unit receives and processes the light signal to detect objects in the surroundings of the system. A control unit controls, particularly synchronizing, the first light source, the photo detector and/or the signal processing unit. The system further includes a test unit for testing the photo detector and the signal processing unit. The test unit a second light source for sending a test light signal within the system to the photo detector.
