  • Apparatus for optically determining the profile and/or upper surface properties of flat workpieces in a wide belt abrading machine
    Patent number: 7605927
    Abstract: An elongated bar shaped housing contains an optical sensing apparatus with at least one light source to create a sensing beam and a deflecting arrangement which moves the sensing beam back and forth between the longitudinal ends of the housing. One of the walls of the housing has an output window extending in the longitudinal direction of the housing for the sensing beam and an input window parallel to the output window for the sensing beam reflected from a workpiece or its support. In the housing behind the input window there is a strip shaped light receiving arrangement with a plurality of optical sensors, as well as an evaluation unit connected to the light receiving arrangement to which the output signals of the light receiving arrangement are sent.
