Paper Abstract

Larger depolarization of incident polarized light has been reported for tissues compared to tissue phantoms with matched optical thickness (τ=μs×d, μs being the scattering coefficient and d the physical thickness). We show that this arises because for the sample with larger μs 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.
