The main objective of this book is to present the basic theoretical principles behind modern
fringe-pattern analysis as applied to optical metrology. In addition to this, for the …

Phase retrieval techniques are widely used in optics, imaging and electronics. Originating in
signal theory, they were introduced to interferometry around 1970. Over the years, many …

Phase Estimation in Optical Interferometry covers the essentials of phase-step**
algorithms used in interferometry and pseudointerferometric techniques. It presents the …

A multi-surface phase demodulation algorithm is proposed to measure surfaces of the
transparent plate simultaneously. A non-linear least-squares method based on the trust …

Phase shifting interferometric (PSI) techniques are among the most sensitive phase
measurement methods. Owing to its high sensitivity, any minute phase change caused due …

In this work, we propose a novel technique to retrieve 3D shape of dynamic objects by the
simultaneous projection of a fringe pattern and a homogeneous white light pattern, both …

A method to obtain unambiguous surface height measurements using wavelength scanning
interferometry with an improved repeatability, comparable to that obtainable using phase …

In this work, a new method for surface extraction in white light scanning interferometry
(WLSI) is introduced. The proposed extraction scheme is based on the Teager-Kaiser …

The intensity distribution of fringe patterns becomes nonsinusoidal in real testing
environments. Thus, the performance of existing phase shift extraction algorithms, which …

In the case that the phase distribution of interferogram is nonuniform and the background/
modulation amplitude change rapidly, the current self-calibration algorithms with better …
