Abstract

The physical principles and methods of creating dynamic photopolarized medium for holography are considered. The medium is based on the phenomenon of the electron photopolarization of the oriented charge-transfer complex molecules. The photopolarization transforms the molecular complexes with life time 10^-4 - 10^-9 s into ion-radical form. It is shown that such photopolarizated medium can achieve speed of response equal to 10⁴ - 10⁸ Hz by high values of the photosensitivity (10⁶ cm²/J), the resolution (1000 mm^-1), and the diffraction efficiency (34%). The medium is of interest for creation of an optical computer's memory, optical memory for real-time correlative information processing, formation of interconnections in optical neural networks, and light beam control.
