The capability of polyvinyl alcohol-acrylamide photopolymer materials to obtain angularly multiplexed holographic gratings has been demonstrated [Appl. Phys. B 76, 851 (2003)]. A combination of two multiplexing methods--peristrophic and angular multiplexing--is used to record 60 holograms. An exposure schedule method is used to optimize the capability of the photopolymerizable holographic material and obtain holograms with a higher, more uniform diffraction efficiency. In addition, because of this exposure schedule method, the entire dynamic range (M#) of the material will be exploited, obtaining values of approximately M# approximately 9 in layers approximately 800 microm thick.
聚乙烯醇 - 丙烯酰胺光聚合物材料获得角度复用全息光栅的能力已得到证实[《应用物理B》76, 851 (2003)]。采用两种复用方法——周向旋转复用和角度复用——的组合来记录60幅全息图。使用曝光调度方法来优化可光聚合全息材料的性能，并获得具有更高、更均匀衍射效率的全息图。此外，由于采用了这种曝光调度方法，材料的整个动态范围（M#）将得到利用，在厚度约为800微米的层中获得约M#约为9的值。
