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.
