| 中文摘要 | 本论文在综述光全息存储技术发展和有机光致聚合物材料的光存储原理、材料性能和当前光聚物材料的研究方向的基础上，主要论述了作者在双波长光聚物材料及波长复用和反射全息存储方面的研究工作：1．探讨了红光敏感光聚合物材料的聚合原理，对红光敏感光聚物的各组成进行优化分析；在优化材料的组分后，我们结合光聚物材料的记录机理，较详细的分析了该种材料的厚度，记录光的空间相干频率和分光比等的变化对材料全息存储性能的影响和原因，并就全息存储的要求提出相应的改进方向。最后我们用该材料完成了模拟信息和数字信息的透射全息存储实验。2．讨论一种的以聚乙烯醇为粘结剂，丙烯酞胺和亚甲基双丙烯酞胺作为单体，赤鲜红和亚甲基蓝作为光引发剂，三乙醇胺作为共引发剂的光聚物材料，能同时对红光和绿光都敏感。3．提出一种光纤引导的波长复用全息存储光路，在此光路上，用我们制备的红绿光敏感的光聚物作为记录介质，实验了波长复用全息存储。4．提出和实验了一种共焦反射全息存储方案，利用两束聚焦后的高斯光束代替通常使用的平面光束来完成全息存储。5．由于反射全息存储与透射全息存储对材料的要求不同，我们讨论了反射全息存储系统中的性能，改进了我们的基于丙烯酰胺为单体的光聚物材料。最后，利用我们的光聚物材料在各种光路上实现了共焦反射全，息存储。 |
| 英文摘要 | The studies of photopolymer holographic recording material sensitized to two wavelengths and reflection holography are mainly described. At the same time, the author presented the progress of holographic storage technology, the principle of the storage of photopolymer, the performance of materials and investigative aspects of modern photopolymers: 1. We investigated the principle of the photopolymerization of a red-sensitive prepared by ourselves, optimized each component and studied the effect of its variation. Then from the recording principle of the photopolymer we studied in details the influence of thickness, the spatial frequency and the ratio of intensity on holographic storage. The way to enhance the performance of material is also presented according to the request of holographic storage. Lastly we finish of simulation holography storage and digital holography storage with it. 2. We discussed a novel type of photopolymer holographic recording materials sensitized to red light and green light which consists of acrylamide and N, N'-Methylenebisacrylarnide as monomer, triethanolamine as charger transfer agents, polyvinylalcohol as polymeric binder, and Erythrosine B and methylene blue as sensitizer. 3. An optical path of holographic storage with fiber leading and wavelength multiplexing is presented. We experimented the wavelength multiplexing with our photopolymer material, this material is sensitive to red light and green light. 4. We experimented a novel scheme of confocal reflection holographic storage in which plane wave of recording beam and reading beam are substituted with two counter propagating Gaussian beams. 5. Since reflection holography storage and ransmission holography storage have different demand with recording material, we discussed and improved the characteristics of holographic material. This photopolymer contains the acrylamide monomer. Finally the confocal reflection holographic storage is carried through. |
