Abstract:
1. A method for the detection of an object by means of an optoelectronic apparatus comprising: generating light rays by a light source that are incident onto an object as a light bead; detecting the light rays scattered back and/or reflected from the object by a receiver arrangement in accordance with a triangulation principle; outputting an object detection signal including information on a scanning distance between the apparatus and the object, with the light rays acting on a pixel array consisting of photodetectors via an imaging element in the receiver arrangement, wherein the imaging element is only an array of individual imaging elements positioned before the pixel array, said array generating a received signal pattern on the pixel array corresponding to a plurality of mutually spaced apart images of the light bead; determining the information on the scanning distance from the received signal pattern, wherein the position of at least two images of the light bead is determined in the received signal pattern, with the respective position of an image being associated with that individual imaging element which has generated the respective image, and wherein the scanning distance is determined from at least one distance between the positions of respective images of the light bead generated from different individual imaging elements.
