摘要

A non-contacted optical instrument for the simultaneous measurement of the average surface roughness (R_a) and the number of peaks per inch (PPI) has been developed. The measurement is based on the scattering theory of light on the rough surface. Both the amplitude (R_a) and frequency (PPI) parameters of the surface roughness measure by optical method are the same as the values measured by conventional stylus method. The optical method can realize the online measurement of moving objects and obtain the fully information of the surface roughness.
