[EN] PROBLEM TO BE SOLVED: To provide a photoelectric sensor for detecting an object within a three-dimensional monitoring area having a plurality of scanning areas.SOLUTION: The photoelectric sensor comprises: a light-emitting unit for emitting an emission beam, the unit including a light emitter for generating the emission beam and a beam divider for dividing the emission beam into a plurality of partial emission beams spatially separated from each other; a light-receiving unit having a spatial resolution provided with a plurality of light-receiving areas to generate a received-light signal from the emission beam diffusion reflected or directly reflected from a monitoring area, each of the light-receiving areas being disposed for one scanning area so that only the emission beam diffusion reflected or directly reflected within a scanning area is received by the light-receiving area; a scanning device capable of rotating around the axis of rotation, the scanning device periodically changing the radiation direction of the emission light and changing the light-receiving direction of the light-receiving unit synchronously therewith; and an evaluation unit for detecting an object on the basis of the received-light signal.SELECTED DRAWING: Figure 1 |
