Depolarization of light in biological tissues: Affect the polarization state by flow and estimation of flow rates

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Recently in phototherapy the use of diodes and broadband light devices instead of lasers was suggested for economical and practical reasons. It has been argued that lasers have no preference over diodes since they lose their coherency and polarization once penetrating into biological tissues. In this talk we have for the first time experimentally validated the conditions that affect the polarization state of light when laser illumination is propagated through a biological tissue with and without a flow. In additional we will present physical modeling showing that illuminating a flow in a medium with linear polarized light can be highly correlated to the direction and rate of the flow through that medium.
