Abstract

The anisotropy induction by light in self-induced molecular aggregations ensemble of azodyes has been studied. In the dynamic regime of anisotropy photoinduction the video-microscopy investigations of the film having photoinduced anisotropy in the crossed polarizers have been conducted. It is shown that image formation herein can be carried out in the way of light modulation of the granular anisotropy integral area of the film. According to an active light exposition, both the concentration and sizes of molecular aggregates having photoinduced anisotropy are being modulated.
