摘要
制备了一种以番红花红T为光敏剂的新型全息存储材料,实验结果表明,该材料具有较高的衍射效率、曝光灵敏度和较大的折射率调制度等,最大衍射效率约38 .5 %,折射率调制度为0 .547×10-3,在存储介质膜中存储了模拟全息图像,再现图像有较好的保真度,说明该材料适合用作高密度体全息存储介质。
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.
