Abstract
The invention relates to an optoelectronic sensor comprising an integrated arrangement of a plurality of light emitting diodes arranged in the region of an optical receiving system for the illumination of a sensing region, with beam-shaping optical elements being associated with the light emitting diodes. The beam-shaping optical elements have optical properties which differ from one another and are dependent on their relative position to the optical receiving system. Furthermore, the beam-shaping optical elements have a wedge shape, with in each case precisely one wedge element or regions of up to four adjacent wedge elements being associated with the light emitting diodes.
