【摘要】 研制了一种以环氧树脂为成膜树脂的光致聚合物材料,研究这种材料全息存储性能特别是复用存储性能,给出了确定适用于该材料的复用存储等衍射效率曝光时序的步骤,包括利用实验数据对数学模型进行拟合的方法。在同一位置角度复用存储了30幅全息光栅,实验结果表明光栅衍射效率的均匀性有了明显的改善。更多还原

【Abstract】 A new epoxy resin-photopolymer made by Technical Institute of Physics andChemistry, Chinese Academy of Sciences is reported. Holographic properties, especiallymultiple recording characteristics of this material are studied. One method of calculatingexposure schedule for multiplexing holograms in photopolymer with equal efficiency isinvestigated. Using the exposure schedule derived with this method, 30 holograms aremultiplexed at a single location by angle multiplexing, and the uniformity of theirdiffraction efficiency was remarkably improved.更多还原
