Abstract: A method for operating an optical light sensor for the detection of objects present in the monitored region in which light signals are transmitted into the monitored region in specific time intervals. The transmitted light signals and also the interference signals which occur are received and are evaluated for the detection of objects present in the monitored region, with the transmission reception of the light signals, and also the reception of the interference signals, respectively taking place in time sequential frame intervals. In the absence of an interference signal within a frame interval the transmission of the light signal takes place at the end of the frame interval defining a normed transmission timepoint for the respective light signal. On the occurrence of an interference signal within a frame interval the transmission of the next light signal is delayed timewise relative to its normed transmission timepoint. Furthermore a light sensor of this kind is described.
