Paper Abstract

A novel method for simultaneously measuring of form and roughness of the diamond turned surfaces has been developed. A laser beam has been applied to scan the surface under test the scattering patterns have been received by a CCD array with 2048 sensor elements the deviation of the specular reflection gives the information of the surface slope which can be integrated to yield the surface form. The surface roughness is described by scattering pattern. Furthermore the scattering patterns can also be used to diagnose the working conditions of the machine which is used to manufacture the optical surface under test. Finally some factors which have influences on the light scattering method have also been discussed. I .
