Transmission of a pulsed polarized light beam through thick turbid media: numerical results.

We present numerical results on the change in polarization state of light pulses transmitted through thick turbid media. These results were obtained with a modified version of a previous Monte Carlo code that takes into account depolarization introduced by multiple scattering. The results have shown that for scattered received power pulse shape, polarization and total received power mainly depend on the transport cross section, σ(d), of the medium. The effect of the angular field of view of the receiver or of the distance between the diffusing medium and the receiver is shown, whereas the effect of the lateral displacement of the receiver elements proves to be of minor importance. An example of measurements showed a good agreement with numerical results, indicating the adequacy of our numerical code.
