Abstract
Real-time holographic gratings were optically recorded with a pair of interferential He-Ne laser beams (632.8Â nm) in poly(methylmethacrylate) (PMMA) film containing 6â²-piperidino-1,3,3-trimethylspiro[indolino-2,3â²-[3H]naphtha-[2,1-b][1,4]oxazine] (SO-1) pre-irradiated by ultraviolet light. The transformation from SO-1 to photomerocyanine (PMC) was studied in detail. PMC was observed in two forms. The holographic characteristics of the recorded gratings were dependent on the polarization direction of the recording beams. Reversible holograms were recorded in the medium by modulating UV light.
