Optoelectronic apparatus and method of operating the optoelectronic apparatus
First Claim
1. A method for the detection of an object, comprising:
- transmitting light in the direction of a reflector (2) using a transmitter (1);
reflecting the transmitted light at the reflector (2);
imaging the reflected transmitted light as a reflector image (11) on a detection region of a receiver (9) with at least one-dimensional spatial resolution, wherein the reflector image is detected by said receiver;
evaluating the detected reflector image;
generating an object detection signal when an at least partial interruption of the transmitted light is recognized based on the evaluation of the detected reflector image;
detecting a light object incident onto the receiver. (9) outside of a detection region (23) using said receiver;
examining the light object for predetermined object properties;
classifying the light object as one of a reflector image and an interfering light object based on the object properties determined; and
in the case of a classification as an interfering light object, determining a movement of the interfering light object on the receiver (9), wherein the generation of the object detection signal is carried out in dependence on the determined movement of the interfering light object.

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.
