Transmissive volume holograms in a polymeric medium with phenanthroquinone

This paper presents the results of holographic studies of a new volume photosensitive polymeric material that makes it possible to carry out postexposure amplification of recorded holograms. The: dependences of a number of parameters of transmissive holograms on postexposure heating time are obtained. A technique is proposed for determining the phase modulation, and the anisotropy of the phase modulation of the resulting holograms is explained. It is shown that at spatial frequencies of the order of 1000 lines/mm, the material makes it possible to obtain transmissive holograms with high phase modulation (more than pi rad). The fact that the angular selectivity of the resulting holograms is (1-2) x 10(-3) rad makes this a promising material for holographic optical elements such as narrow-band spectral and angle selectors.
