Abstract

A new technique for the measurement of surface roughness based on the Intensity fluctuations of laser light backscattered form a moving surface has been introduced. The developed method will be quite useful for evaluating the surface quality under machining with more detailed Information by detecting the surface roughness along both directions simultaneously.
