Abstract
A laser scanner (10) is provided which has a light transmitter (12) for transmitting a light signal (16) into a monitored zone (20), a light receiver (26) for generating a received signal from the light signal (22) remitted by objects in the monitored zone (20), a movable deflection unit (18) for the periodic deflection of the light signal (16, 22) to scan the monitored zone (20) in the course of the movement, and an evaluation unit (34) for detecting the objects with reference to the received signal and for testing the signal path from the transmission of the light signal (16) up to the detection of the objects. In this respect, the evaluation unit (34) is configured also to detect objects in angular positions of the deflection unit (18) in which the signal path is tested.
