Polarized light propagation in multiply scattering media exhibiting both linear birefringence and optical activity: Monte Carlo model and experimental methodology.

摘要: A Monte Carlo model for polarized light propagation in birefringent, optically active, multiply scattering media is developed an effort to accurately represent the of biological tissue. The employs Jones N-matrix formalism combine both linear birefringence and optical activity into a single effect that can be applied photons as they propagate between events. Polyacrylamide phantoms with strain-induced birefringence, sucrose-induced activity, polystyrene microspheres particles are used experimental validation. Measurements made using Stokes polarimeter detects scattered different geometries, compared results simulations run similar parameters. show close agreement measurements calculations exhibiting turbidity well turbidity, activity. Other scattering-independent polarization properties incorporated formalism, enabling quantification effects via accurate polarization-sensitive model.
