Abstract

Phase unwrapping is a very important processing step in phase shift interferometry. In this work, we propose a new method which combines the branch-cut method with error correcting. The method can avoid the propagation of the phase errors and have higher reliability. The experiment proves the proposed method is feasible and effective.
