A new optical profiler for surface roughness measurement developed by the authors is described in this paper. Based on an analyses of phase shifting error in phase shifting interferiietry a new algorithm for eliminating the effect of the error is presented. The experiments show that the development of this instrument is successful and it has a vertical resolution of 1 nni lateral resolution of 0. 42 Itm and a repeatability of Ra 0. 6 nni.
