On the basis of a new polyurethane with azobenzene dopants, recording media for polarization holography have been created, and their information properties have been studied when recording holograms of a plane wavefront. It has been found that the recording and relaxation times of holograms are short, and it is defined by the processes of trans-cis-isomerization of azobenzene groups without the formation of the surface relief in the polymer film. The obtained results are of practical interest in the choice of photosensitive materials for holographic recording media for dynamic holography.
