TLDR
In this article, a polarized light camera was employed to simultaneously capture the photoelastic patterns of the dark and bright fields under circular polariscope, and based on the light intensity difference of these patterns in the entire loading process, a method of quantifying fringe orders was proposed.About:

New computational hybrid three-wavelength-based approach of phase shifting for analyzing the stress field in photoelasticity studies
TL;DR: This new computational hybrid approach calculates the stress field by extract the phase steps from RGB color channels of a photoelastic color image by integrated the load stepping strategy with a computational hybrid phase algorithm, hence only bright field images are required.
