Abstract

photoinduced effects in thin light-sensitive films on the basis of the chlorous and iodous silver. the dissertation in many script form is submitted for a Candidate Degree in physical and Mathematical Science, spesiality 01.04.05 - optics, Laser physics. Kharkov state University. Kharkov, Ukraina 1995. 8 scientific works is maintained. a light-sensitivity effects of a photoadaptation, Hershel (EG) and periodic structures (ps) were investigated in film on basis of AgCl and AgI. It is shown; the light-sensitivity of the films take place at the disperse state of a Ag admixture, in the AgCl-Ag films the frequency-interference PAD is displayed but in the AgI-Ag EG: frequency PAD promotes the PS generation. A hologram of a visible spectrum, connected with the PS generation, was prepared first. A connection was established of the PS with anisotropy of refractive index of substrates. The PS, induced as a result of a two-photo absorption, were received first in AgI films.
