  • Measurement of surface roughness
    Patent number: 3971956
    Abstract: The roughness of a surface is determined by directing a laser beam, or other electromagnetic radiation, onto a number of small areas of the surface in turn and measuring intensity of radiation scattered from the small illuminated areas with detectors arranged at a number of angles to the surface. Both the height of surface irregularities and average statistical wavelength may be found without physical contact with the rough surface.
