Dynamic 3-D nano-scale surface profilometry using stroboscopic interferometry was successfully developed. An optical microscopy based on stroboscopic interferometry was developed to achieve full-field vibratory out-of-plane surface profilometry and s

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 hi

This study proposes the auto-focusing procedure and the scan-range determining algorithm for white-light scanning interferometry. During white-light scanning interferometry, the interference fringe must be located and to the best-focus interferogram

It is necessary and important to find the focal plane in order to locate where the interference fringe is, and to determine the vertical-scan range prior to the scanning operation for an SWLI. A novel scheme is proposed in this paper for simultaneous

The results of combining the wrapped phase with the fringe order of this phase to increase the precision of white-light interferometry at high scanning speed are presented. Monochromatic phase data are calculated using the Fourier method and the frin

A new profiling algorithm is proposed for the scanning white-light interferometry. A series of white-light interferograms are acquired by traditional vertical scanning process. The collected intensity data of the interferograms are then Fourier-Trans
