Monte Carlo Simulations of Spatial Patterns of the Degree of Polarisation for Backscattering Lights in Turbid Media with Birefringence

In Optical Coherence Tomography (OCT) technology, as contrast mechanism and a characterization of the optical polarization properties of a biological tissue，it is very important of polarization in which birefringence is one of the relative phenomena. We analyzed the propagation of polarized light in a linearly birefringent turbid medium and simulated the degree of polarization of diffusely backscattered lights using the Stocks Mueller formalism and Monte Carlo algorithm. Statistical distributions of the changes of polarization in the turbid medium with different birefringent parameters are demonstrated.
