Title: Robust phase unwrapping algorithm for 3D profile measurement applications
Author: Meiqi Fang, Hong Zhao*, Chunwei Zhang, Yueyang Ma and Cahngquan Zhou
Abstract: Phase unwrapping is a significant procedure that has raised a great interest in many coherent imaging systems. What we believe to be a new phase unwrapping algorithm, is described and tested. The method starts from the fact that 2D wrapped phase distribution can be regarded as a response to two orthogonal 1D direction excitation signals. This suggests a cepstrum analysis to be implemented in the phase unwrapping problem. Experimental results both from the fringe projection profilometry and DENSE MRI also confirmed the validity of our approach. In fact, this proposed method is possible to attain a fast and practical phase unwrapping solution with enhanced noise robustness.
