TLDR
In this paper, a carrier fringe technique for photoelasticity stress analysis is described and verified experimentally, where linear carrier fringes generated by using a quartz wedge are superimposed on fringes formed by the stressed model and the resultant fringe pattern is captured using a charge coupled device camera and stored in a digital frame buffer.About:

Fourier-transform method of fringe-pattern analysis for computer-based topography and interferometry
TL;DR: In this article, a fast Fourier transform method of topography and interferometry is proposed to discriminate between elevation and depression of the object or wave-front form, which has not been possible by the fringe-contour generation techniques.
