When circularly polarized light illuminates a scattering medium, depolarization due to multiple scattering depends mainly on the particle size of the scatterers. In the previous study, we revealed the correlation between the ratio of particles with two different diameters in an aqueous suspension medium and the changes in the circular polarization degree of the scattered light experimentally and computationally. In this paper, we demonstrate the evaluation of the ratio of particle size in solid phantoms which imitate diffuse cancers, such as scirrhous gastric cancer, with the aim of improving diagnostic imaging techniques in medical applications.
