TLDR
In this article, a simple direct technique to determine a broad set of elastic moduli is presented based on compression testing of a prism sample, which is used to measure the full-field deformations that allow the determination of Young's moduli and all six Poisson's ratios for the three orthogonal directions based on a single sample.About:

Strain analysis for moiré interferometry using the two-dimensional continuous wavelet transform
TL;DR: In this paper, the two-dimensional continuous wavelet transform was used for the automated analysis of the moire interference fringe pattern. But, this method is hardly applicable to the analysis of fringe pattern, which includes large displacement range or discontinuities.
