Abstract

This work shows the most used techniques for fringe analysis and presents a novel technique based on sub-fringe integral method with carrier frequencies, for phase retrieval. This method integrates one fringe into various subfringes to obtain the phase value. Several experiments were performed to obtain the information of flatness and profile from the surface to be analyzed.
