Device for optoelectronic monitoring of objects and detecting of light beams scattered at a faceplate
First Claim
1. Device for optoelectronic monitoring of objects, with a transmitting unit (12) that transmits light beams (24) in a structured illuminating pattern, with a receiving unit (14), that contains an image recorder (28) on which the object (26) illuminated with structured illuminating pattern is recorded, and with a housing (10) in which the transmitting unit (12) and the receiving unit (14) are located and which has a faceplate (16) for the transmitting unit (12) and the receiving unit (14), characterized in that the transmitting unit (12), the receiving unit (14), and the faceplate (16) are positioned in the housing (10) so that the light beams that are directly reflected at the faceplate (16) do not travel into the image recorder (28) of the receiving unit (14) and so that beams from the transmitting unit (14) separately from the recording of the object (26) by means of receiving optics (30) included in the receiving unit (14),characterized in that the image recorder (28) contains a matrix arrangement of photoelectric elements and that light beams (24) diffusely scattered at the faceplate (16) are recorded by the image recorder (28) separate from recording of the object (26).

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).
