A wide range of interferometric techniques recover phase information that is mathematically
wrapped on the interval (-π, π]. Obtaining the true unwrapped phase is a longstanding …

Spectral modulated interference fringes are observed in the form of the periodical
modulation of a broadband spectrum at the output of an interferometer provided with a …

A generalized Fourier analysis, by use of an adaptive multiscale windowed Fourier
transform (AWFT), has been presented for the phase retrieval of fringe patterns. The Fourier …

A novel technique called a two-dimensional digital phase-locked loop (DPLL) for fringe
pattern demodulation is presented. This algorithm is more suitable for demodulation of fringe …

A novel technique called an iterative linear digital phase locked loop (DPLL) for fringe-
pattern demodulation is presented. The proposed technique has better noise immunity than …

Retrieving information in real time from fringe patterns is a topic of a great deal of interest in
scientific and engineering applications of optical methods. This paper presents a method for …

It is now widely acknowledged, among communities of researchers and engineers of very
different horizons, that speckle interferometry (SI) offers powerful techniques to characterize …

Temperature monitoring and control of a convex molten polymer sheet and surrounding
cooling air flows are demanded in order to improve both the productivity and the quality of …

A novel technique called a two-frame digital phase-locked loop for fringe pattern
demodulation is presented. In this scheme, two fringe patterns with different spatial carrier …
