EVALUATION OF OPTICAL ANISOTROPY OF ALUMINA NANOPOROUS FILMS BY STOKES-POLARIMETRY AND COHERENCE MATRIX METHODS
Abstract
The effect of the amplitude anisotropy of nanoporous alumina films and depolarization of the transmitted radiation on the phase shift between the orthogonally polarized components of the transmitted radiation was studied using Stokes-polarimetry and coherence matrix methods. The test samples were illuminated by linearly polarized radiation with the polarization azimuth of 45° in the wavelength range from 400 to 1000 nm. The systematic error introduced into the phase shift between the orthogonally polarized components of the transmitted radiation because of neglecting the material amplitude anisotropy and the depolarization of the transmitted radiation was established.
