  • Device for optically measuring surface properties
    Patent number: 7295299
    Abstract: An apparatus for optical measurement of surface properties wherein a light spot is produced by an illumination device and reflected light is measured by a multiplicity of optical sensors. In the evaluation, the individual signals of sensors, at least a multiplicity of signals of comparatively small groups of sensors is taken into account. Thus, an extrapolation of the detection angle region is possible.
