Paper Abstract

A simple empirical method is presented to determine the scattering coefficient µs from backscattered polarized images of turbid media. It uses the ratio, pixel by pixel, of two images that are the second and the first backscattered Stokes parameter images Q and I, respectively. Taking this image ratio, then integrating it over the azimuth angle, we get a function depending on the distance from the light entrance point. This function has a maximum. Using Monte Carlo simulations, for a fixed reduced scattering coefficient µ′s and for an anisotropy factor g varying between 0 and 0.8, it is found a linear relationship between the scattering coefficient µs and the inverse of the maximum position of this function.
