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.

Abstract: An optical scanner comprises a light transmitter for transmitting a light beam; a beam deflection unit that is configured to deflect the transmitted light beam in a periodically varying manner with a predefined period duration in order to scan a detection zone; a light receiver for receiving reflected light; and an electronic control device for controlling the beam deflection unit. The electronic control device is configured to automatically increase or decrease the period duration by a difference amount with respect to a nominal value before or during the operation of the optical scanner in order to counteract crosstalk between the optical scanner and a further optical scanner.

Abstract: An optical detection apparatus is configured to transmit pulses into a detection zone after one another in different directions which follow one another in a scanning direction over a scanning angle, to receive the radiation of the transmitted pulses returning from the detection zone, to generate a received signal with respect to each transmitted pulse, said received signal depending on the variation with time of the returning radiation of the transmitted pulse, and to average the received signals of a group of transmitted pulses to generate an averaged received signal. The angular extent relating to the scanning angle of at least one transmitted pulse of the group at a spacing from the detection apparatus disposed within the detection zone is at most 25 times the size of the angular spacing relating to the scanning angle between two transmitted pulses of the group directly adjacent one another in the scanning direction.
