Designing phantoms to accurately replicate circular depolarization in biological scattering media

摘要

We introduce an iterative method for designing optical phantoms that are able to replicate the depolarization profiles of various target media, including colloidal suspensions of Intralipid, bovine milk, and ex vivo samples of ovine kidney cortex tissue. The designed phantoms comprise spherical scattering particles with fine-tuned size distributions and are capable of simultaneously reproducing spatially resolved intensity measurements and depolarization measurements of target media when illuminated with circularly polarized light.
