中文摘要：

对于体全息来说,存储材料的体积与所能存储的信息容量有关。采用热致聚合方法制备了厚度分别为0.5mm、1.0mm、1.5mm、2.0mm的菲醌掺杂的聚甲基丙烯酸甲酯（PQ/PMMA）光致聚合物材料。探测并分析了材料样品对不同波长的光吸收特性以及不同厚度材料的全息性能。实验结果表明,厚度的变化对材料的光致双折射值影响较小,而对衍射效率的影响较大。

英文摘要：

For volume holographic, the volume of storage materials relate to the information capacity can be stored. The PMMA thermal polymerization preparation thickness is 0. 5 ram, 1.0mm, 1.5mm, 2.0mm phenanthrenequinone- doped-PMMA （PQ/PMMA） photopolymer materials. The characteristics of material samples absorpting different wave- lengths of light and the holographic property of materials with different thickness are detected and analyzed. The experi- mental results show that the change of thickness has less effect on the birefringence value of the material, while it has greater influence on the diffraction efficiency.
