Abstract: An optoelectronic scanner for detecting objects in a monitored zone is provided that has a light transmitter for transmitting at least one light beam, a movable deflection unit for the periodic scanning of the monitored zone by the at least one light beam, a light receiver for generating a received signal from the light beam remitted by the objects, and a control and evaluation unit that is configured to acquire information on the objects in the monitored zone from the received signal and to recognize dazzling of the light receiver and to switch into a dazzle state in the case of dazzle preventing safe detection. In this respect, first phases with dazzling and second phases without dazzle are recognized and a decision is made with reference to the distribution of the first phases and second phases whether dazzle prevents the safe detection.

Abstract: The present invention relates to a method of operating a scanner for monitoring an least two-dimensional protected field that is divided into a plurality of cyclically scannable monitored fields, wherein the scanner comprises at least one light transmitter and at least one light receiver. The invention further relates to a scanner for monitoring an at least two-dimensional protected field.
