摘要
文章指出对反射体积相位全息图衍射效率起决定作用的是光栅的折射率振幅,分析了光栅和散射物体全息图片在微观结构上的不同,因而衍射效率也不同,接着从两个方面(曝光参数、激光器性能)分析了影响折射率振幅的因素。文章还指出衍射效率常和信噪比是相互制约的,只有适当选择参数才能寻求最佳效果。
The paper pointed out that the diffraction efficiency on volume hologram of the phase place is relied on amplitude of refraction rate of the grating, Compared with holographic picture of the grating and scattering objects in the micro structural, and showed the diffraction efficiency different. We analysed the factors in influent the amplitude of refracting rate from two respects （the exposed parameter, the performance of the laser instrument）. The results show that diffraction efficiency be restricted with SNR, and only choose the parameter. properly, the best effect can be received.
