The results of experiments on obtaining holograms on photochromic organic films are presented. The composition that represents a solution of an organic dye is deposited on a glass plate to form a thin film. The thickness of the film is 20-30 μm. The basic limitation to the quality wavefront reconstruction images is accounted for by the noise generated by the granular structure of the recording medium. It became apparent especially for the small-size holograms. The holograms obtained on photochromic films are free from such noisz. A high quality of the reconstructed image is explained by the nongranular structure of photochromic material (the resolution cell is much smaller in comparison with the wavelength of light).
