Robust profilometer for the measurement of 3-D object shapes based on a regularized phase tracker

A robust profilometer is proposed to measure 3-D object shapes based on a r egularized phase tracker that is capable of demodulating fringe patterns wi th a high noise presence and broad bandwidth due to the object shape. As sh own herein, the technique acts as an adaptive filter and is capable of givi ng the detected phase continuously so that no further unwrapping process is required. Experimental results of real surface profiles are presented. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
