Digital photoelasticity – A comprehensive review
TLDR
This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.Abstract:
Digital photoelasticity has rapidly progressed in the last few years and has matured into an industry-friendly technique. This review thematically classifies all the developments in digital photoelasticity and highlights the relative merits and drawbacks of the various techniques. The overall objective is to provide enough information and guidance to allow an end-user to make an informed choice on the type of technique to be used in a particular situation.read more

Fourier fringe analysis: the two-dimensional phase unwrapping problem.
TL;DR: A new phase unwrapping algorithm is described that uses local phase information to mask out those parts of the field that cause inconsistencies in the unwraps and can produce an approximately correct unwrapped.

Demodulation of a single interferogram by use of a two-dimensional regularized phase-tracking technique
TL;DR: A two-dimensional regularized phase-tracking technique that is capable of demodulating a single fringe pattern with either open or closed fringes and gives the detected phase continuously so that no further unwrapping is needed over the detectedphase.
