Paper Abstract

A random phase shift atgorithm based on the principLe of phase-measuring profiLometry with a projected sinusoidaL grating to 360 measurement-of the surface topography of 3-D diffuse objects is presented. In contrast to phase shifting interferometry this method eLiminates the needs of vibration isoLation thus an on-Line or in-process amasurement could be executed. 1.
