摘要：
It is shown how scattering media may allow to confer high polarization degree (DOP approximate to 0.75) to an incident depolarized beam (DOP approximate to 0). The statistics of the polarization degree versus scattering directions or space location are investigated with a CCD camera at a speckle resolution. Numerical calculation and experimental data are compared and show high agreement for a sample highly inhomogeneous in the bulk. The probability density function of the DOP follows a 3u(2) variation.
