报道了甲基橙偶氮染料掺杂的聚乙烯醇（ＭＯ／ＰＶＡ）薄膜材料在Ａｒ＋激光４８８．０ｎｍ线预辐照下，用正交线偏振的６３２．８ｎｍ光作为写入光，通过旋转样品，在同一光斑内形成多个取向不同的相位光栅，实现了多重全息存贮的实验结果。在三重图像的存贮中，通过控制每次的写入时间，得到了三个均匀明亮的衍射图像，其平均衍射效率为０．１％。实验发现，该全息图可用红光长时间再现，而仅有较弱的擦除作用。用四能级结构模型对多重存贮的物理机制进行了探讨
Reported that the methyl orange azo dye doped polyvinyl alcohol (MO / PVA) thin film material in Ar + laser 488.0nm line pre-irradiation, with orthogonal linearly polarized 632.8nm light as the write light, by rotating Samples, in the same spot to form a number of different orientation phase grating, to achieve a multi-holographic storage of experimental results. In the storage of triple images, by controlling each writing time, three uniformly bright diffraction images were obtained, the average diffraction efficiency was 0.1%. The experiment found that the hologram can reproduce with red light for a long time, but only a weak erasing effect. The four-level structure model is used to discuss the physical mechanism of multiple storage
