Polarized bidirectional reflectance distribution function by subsurface defects of optical component

Polarized bidirectional reflectance distribution function(PBRDF) of light scattered by subsurface defect(SSD) was derived on the foundation of Jones scattering matrix by use of right handed basis set. Four kinds of PBRDF changing with azimuth angle were calculated and compared at different incident angles, and three-dimensional BRDFpp which indicates p polarized scattered light due to p polarized incident light were obtained at different incident angles. The results show that BRDFpp by SSD depends strongly on incident angle, scattering angle and azimuth angle. The azimuth angle of minimal BRDFpp decreases with the increase of incident angle.
