Dynamic theory of volume holography is used to calculate the variations in the thickness direction of the hologram-constituting refractive-index modulation and the externally observable effects of these variations in electrooptic materials. It is shown that thick holographic gratings may exhibit significant amplitude and grating phase variations with thickness including amplitude sign reversal. These nonuniformities strongly affect holographic grating recording and readout characteristics such as maximum possible diffraction efficiency and angular selectivity. Thus a variety of grating applications will be affected by these nonuniformities.
利用体积全息术的动力学理论来计算构成全息图的折射率调制在厚度方向上的变化以及电光材料中这些变化的外部可观测效应。结果表明，厚全息光栅在厚度方向上可能会表现出显著的幅度和光栅相位变化，包括幅度符号反转。这些不均匀性会强烈影响全息光栅的记录和读出特性，如最大可能衍射效率和角度选择性。因此，各种光栅应用都会受到这些不均匀性的影响。
