The difference in the absorption of two orthogonal linear polarizations was first observed in the investigation of the total internal reflection from the interface azo dye doped gelatin layer - air. This means that there exists a predominant orientation of dye molecules in the emulsion layer. It is very important fact for the problems of adequately holographic registration of polarization characteristics of the light fields. It is especially important also in the creation of holographic diffractive structures with anisotropic structures. Experiment was performed for the actinic radiation of the He-Cd laser (λ = 441.6 nm) for two mutually orthogonal linear polarizations of the light: with oscillations of electric vectors parallel (P polarization) and perpendicular (S polarization) regarding to incidence plane. The result of investigation has shown the difference of total internal reflection for these polarizations at the initial stage of irradiation of azo-dye doped emulsion layer at the incidence angle of the light 450. The different values of the relative intensities of the total reflection (Ir/I0) for the P and S polarizations (0.025 and 0.1 accordingly) indicate to the anisotropy of absorption of the light caused by predominant orientation of dye molecules (POM) in the layer. At the prolongation of exposure with the same wavelength the dichroism of the total internal reflection disappears because of photo transformation of the dye molecules responsible for Weigert effect in these materials.
