Towards RGB photoelasticity: Full-field automated photoelasticity in white light
TLDR
A new full-field method for the automatic analysis of isochromatic fringes in white light, named RGB photoelasticity, which makes it possible to determine retardations uniquely in the range of 0–3 fringe orders.Abstract:
In this paper a new full-field method for the automatic analysis of isochromatic fringes in white light is presented. The method, named RGB photoelasticity, eliminates the typical drawbacks of the classical approach to photoelasticity in white light which requires a subjective analysis of colors and an experienced analyst to acquire and interpret the results.read more

An Arctangent Unwrapping Technique of Photoelasticity Using Linearly Polarized Light at Three Wavelengths
TL;DR: In this paper, a phase unwrapping method using the arctangent function to photoelasticity has been proposed, which overcomes the error associated with the quarterwave plate by using an incident light of different wavelength and does not need an interpolation for the determination of ψ.
