Abstract
The results of investigation of the phenomena ISPh was reported. It was shown that in the given layers after the irradiation of the polarized light with wave-length actinic for the given sensitizer and of the following specific development the photo-induced anisotropy was visualized. It turns out that weakly expressed anisotropy of the latent image multiplied more than on the two order of magnitude. As it was shown in this investigation, the value of the photo anisotropic parameters can changed in wide-ranging after the specific physicochemical treatment: hypersensitizing, specific worked out developers, thermal treatment, fixing (in case of need). Each of the procedure has such essential value, that the separated examination was needed. For example, 20 developing agent per se and large quantity of the different compositions, and also the quantity hypersensitizers was investigated. The photo induced anisotropy maybe measured on the modified spectrophotometers SF-10 or SF-18. To receive experimentally the dependence of the anisotropic absorption, and the light induced birefringence it is necessary to carry out not less than 6 measurements of transmission of the differently oriented irradiated samples (0°; 45°; 90°), placed between parallel and crossed polarizers in the spectrophotometer. Some technological regimes which reduced to the optimization of the parameters of the photo anisotropy are presented. The high stability, the possibility of working in the red region and with the low power energy sources, with the wide controlled characteristics are represented the main advantage of such media. In addition the Schwarzchild effect in the ISPh phenomena is considered.
