Red-green bicolor photoelasticity using a single-color image
TL;DR: In this article, the authors explored the possibility of isochromatic demodulation using the intensity data of only the red and green color planes drawn from a single color image, which would help in avoiding the uncertainties caused due to the blue color plane in RGB photoelasticity.
