Abstract

The work is dedicated to a study of anisotropy photoinduction during the light-stimulated molecular aggregations in organic compounds. The case of gelatin or polyvinyl films saturated by azo dyes is considered. By using the video and spectral techniques, the time-formation picture of optical image is studied. It is shown that in this case the image is formed in a similar way as in silver emulsions in the process of photographing — "with the grain distribution".
