1. An optoelectronic sensor (11) for recognizing object edges (29) of objects (23),
mcomprising at least three light transmitters (15) for generating respective collimated or focused transmitted light beams (21), wherein the light transmitters (15) are arranged such that at least two different spacings (D1, D2, D3) result between two respective light transmitters (15) of the at least three light transmitters (15); comprising at least one light receiver (17) for taking light spots generated by the transmitted light beams (21) on an object (23); and comprising an evaluation unit (25) which is configured, for the recognition of an object edge (29), to carry out a common evaluation
(i) of an image taken by a light receiver (17) of a light spot generated by the transmitted light beams (21) of a first light transmitter (15) of the at least three light transmitters (15); and(ii) of an image taken by a light receiver (17) of a light spot generated by the transmitted light beams (21) of another light transmitter (15) of the at least three light transmitters (15), wherein the pair of light transmitters (15) to be used for the common evaluation can be selected in dependence on a selection criterion from at least two differently spaced apart pairs of light transmitters (15). |
