Recording of holograms on photosensitive polymers

The results are reported of experiments to which holograms were recorded on photosensitive polymers. Phase holograms could be recorded on these materials, which offered the advantage of a high diffraction efficiency. The holograms were recorded in a convergent beam (λ = 0.63 μ) which ensured a high density of recorded information and did not require high laser powers. The photosensitive polymer was sensitized to red light. The results are given of measurements of the sensitivity of the polymer and of the diffraction efficiency of the holograms. A photograph is included of the reconstructed image of a television test card.
