This paper introduces a kind of real time measurement of part surface roughness using laser technique. In this measurement,triangulation measurement is adopted, by using nondiffraction laser beam as light source and high accuracy CCD pickup camera as displacement sensor. The surface roughness value is obtained by computer data processing and real time measurement of surface roughness becomes possible.
