摘要
给出了体积全息图的衍射效率与记录介质吸收系数和厚度的关系,指出必须考虑制做全息图时介质吸收的影响,并提出了改善体积全息图性能的方法.
The relationship between the absorption of medium and the diffraction efficiency of volume holograms is investigated experimentally. It is found that the effects of the absorption by medium must be cousidered during construction of holograms. The way to reform the quality of volume holograms is suggested.
