Abstract:

The relative roughness of a surface, finished with a plurality of uniform parallel grooves, is indicated in a method wherein a a focused beam of light is directed normal to the surface, b a light-sensitive device is disposed to one side of the beam to receive reflected light of the beam from the surface, c relative motion is provided between the beam and the surface, and d the energy of the reflected light received by the light-sensitive device is converted to a visual display whose amplitude is a function of the roughness of the surface.
