Safranine T Sensitized Photopolymer Materials for Holographic Storage
番红花红T敏化的新型光致聚合物全息存储材料(英文)

Safranine T was employed as one of photo-sensitizers of a novel photopolymer material for holographic recording. The experimental results show that the material has high diffraction efficiency and large refractive index modulation. The maximum diffraction efficiency of the photopolymer is about 38.5%, and the refractive index modulation is about 0.547×10-3.The analog holograms are stored in the medium and the reconstructed picture has a good fidelity. It shows that the photopolymer material has the potential for high-density volume holographic storage.
