Abstract

A method to reliably extract object profiles even with height discontinuities (that leads to 2nπ phase jumps) is proposed. Along with the images needed to extract wrapped phase, proposed method uses an additional image formed by illuminating the object of interest by a gray coded pattern for phase unwrapping. Theory and experiments suggest that the proposed approach not only retains the advantages of the original method, but also contributes significantly in the enhancement of its performance.
