利用三维矢量全息技术在单轴取向的偶氮染料掺杂液晶复合材料中诱导出周期性的各向异性结构。利用各向异性记录介质中的偏振干涉和偏振传播两种方式制作了三维矢量全息图。为了获得清晰的洞察三维矢量全息图的光学特性，各种类型的结构诱导通过改变记录光束的偏振状态和入射角。采用时域有限差分法计算了各种类型的三维矢量全息图的衍射特性，理论解释与实验结果吻合较好。
Periodic anisotropic structures were induced by means of a three-dimensional vector holographic technique in an azo-dye-doped liquid crystal composite with uniaxial alignment. The three-dimensional vector hologram was fabricated by both the polarization interference and the polarization propagation in the anisotropic recording medium. In order to obtain clear insight into the optical properties of three-dimensional vector holograms, various types of structures were induced by changing the polarization states and incident angles of the recording beams. The diffraction properties of various types of three-dimensional vector holograms were calculated by the finite-difference time-domain method, and the theoretical explanations were in good agreement with the experimental results.
