Abstract
Larger depolarization of incident polarized light has been reported for tissues compared to tissue phantoms with matched optical thickness (? =?s × d, ?s being the scattering coefficient and d the physical thickness). We show that this arises because for the sample with larger ?s more multiply scattered photons are detected in a narrow collection angle typically used in experiments. These results were verified by time resolved studies on transmitted light as well as by Monte Carlo simulation.
