In this day of digitalization, you can work within the technology of optics without having to
fully understand the science behind it. However, for those who wish to master the science …

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 …

Fringe pattern normalization consists in the background suppression and modulation
normalization of a given fringe pattern, this process gives as a result a pure sinusoidal …

Hybrid single shot algorithm for accurate phase demodulation of complex fringe patterns is
proposed. It employs empirical mode decomposition based adaptive fringe pattern …

A simple but effective approach for the demodulation of a single fringe pattern is proposed.
The phase with an undetermined sign is directly obtained by taking the arccosine value of a …

Quadrature operators are useful for obtaining the modulating phase ϕ in interferometry and
temporal signals in electrical communications. In carrier-frequency interferometry and …

A new sequential phase demodulator based on a regularized quadrature and phase tracker
system (RQPT) is applied to demodulate two-dimensional fringe patterns. This RQPT system …

Two new two dimensional (2-D) complex operators for estimating the energy and orientation
of 2-D oriented patterns are proposed. The starting point for our work is a new 2-D extension …

Fringe pattern based measurement techniques are the state-of-the-art in full-field optical
metrology. They are crucial both in macroscale, eg, fringe projection profilometry, and …

Fringe orientation can direct the processing of fringe patterns and provide basic information
for understanding the fringe patterns. The gradient method is popularly used for its …
