The Scattering of Light from Thin Polymer Films: Multiple Scattering. II. Effect of Depolarization.

摘要

A procedure is described to include the effect of depolarization of the originally plane-polarized incident light beam as it passes through a thin polymer sample on the intensity of multiple light scattering. The multiple scattering gives rise to polarization scrambling in which, for example, H sub nu scattering measurements involve multiple scattered rays which may have undergone some V sub nu scattering. These phenomena reduce the angular dependence of scattering since large intensities originally occurring at small values of theta are rescattered so as to enhance intensities at other angles. Correction factors for both H sub nu and V sub nu scattering are presented.
