Abstract
A device for optoelectronic monitoring of an object (26) contains a transmitting unit (12) and a receiving unit (14) that are located in a housing (10) covered by a faceplate (16). The transmitting unit (12) emits light beams (24) in a structured illuminating pattern. The illuminating pattern of the illuminated object (26) is recorded on an image recorder (28) by the receiving unit (14). Soiling (38) on the faceplate (16) is indicated by recording the light beams (24) diffusely scattered at the faceplate (16) on the image recorder (28).
