  • Method and apparatus for the optical detection of the roughness profile of a material surface
    Patent number: 4973164
    Abstract: A method and also an apparatus is described for the direct optical detection of the roughness profile of the material surface (10) in which a light bead (14) is generated on the material surface (10) and the reflected light is passed to a light receiver arrangement (16). The angle of reflection of the reflected light and thus the respective surface inclination value is determined for each scanned point of the material surface (10). To determine the angle of reflection the direction of the center of gravity of the scattered reflected light is formed in each case. The desired roughness profile is subsequently reconstructed from the inclination values that are obtained.
