On the reversibility of Weigert's effect in azo-dye-colored materials.
The dynamic process of the multiple generation and deletion of anisotropy with linearly polarized actinic light is investigated experimentally in azo-dye-colored gelatin. The results of the investigation are in good compliance with the possible mechanism of anisotropy generation in the azo-dye-colored materials proposed by the author [Z. V. Wardosanidze, Appl. Opt. 45, 438-444 (2006)].
