Transmissive volume holograms in a polymeric medium with phenanthroquinone

This paper presents the results of holographic studies of a new volume phot osensitive polymeric material that makes it possible to carry out postexpos ure amplification of recorded holograms. The: dependences of a number of pa rameters of transmissive holograms on postexposure heating time are obtaine d. A technique is proposed for determining the phase modulation, and the an isotropy of the phase modulation of the resulting holograms is explained. I t is shown that at spatial frequencies of the order of 1000 lines/mm, the m aterial 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 sel ectors.
