Abstract
A method for the detection of an object includes transmitting light in the direction of a reflector by a transmitter. The transmitted light is reflected by the reflector and is imaged as a reflector image and is detected by the receiver. The reflector image is evaluated and an object detection signal is generated if an at least partial interruption of the transmitted light is recognized. A light object incident onto the receiver outside the detection region is detected by the receiver, is examined for predetermined object properties and is classified as a reflector image or as an interfering light object based on the object properties. In the case of a classification as an interfering light object, a movement of the interfering light object on the receiver is determined and the generation of the object detection signal is executed based on the determined movement of the interfering light object.
