Recording of the polarization of light specified by anisotropic crystals with the aid of photoinduced dichroism in photosensitive films

It is shown that photoinduced dichroism in photosensitive AgCl films with Ag granules can be used to record the spectral dependence of the state of polarization specified by anisotropic crystals. The recording of the state of polarization throughout the visible spectral region is favored by the frequency photoadaptation, which is typical of AgCl–Ag films. This effect also determines the good reproduction of color corresponding to the spectrum of the irradiating beam. The results show the feasibility of determining the magnitude of photoinduced dichroism and its dispersion by analyzing the pattern recorded in a film in polarized light.
