Light repolarization by scattering media

TL;DR

This paper investigates how disordered media can induce polarization in unpolarized light, showing that complex scattering media can significantly increase the degree of polarization of incident light.

Contribution

It provides experimental and theoretical analysis demonstrating that disordered scattering media can enhance the polarization of unpolarized light.

Findings

High degree of polarization achieved (average DOP of 0.75)

Excellent agreement between theory and experiment

Complex media can confer polarization to unpolarized light

Abstract

The polarization of a coherent depolarized incident light beam passing through a disordered medium is investigated. The local polarization of the scattered far field and the probability density function are calculated and show an excellent agreement with experiment. It is demonstrated that complex media may confer high degree of polarization (0.75 DOP average) to the incident unpolarized light.
