Fig. 3. (a) An image composed by combining an interference color image and an interference color image rotated by 45 degrees from the same observation area. The composite image can clearly distinguish between particles with similar interference colors. (b) Pseudo-PPL image composed by synthesizing two images in which the upper analyzer and the lower polarizer are parallel. These two images are also rotated 45 degrees from each other. The thin lines in the last image represent the trajectory of marker particles during simple shear deformation experiments.
