本文描述了在各向异性记录介质中形成三维矢量全息图的原理。由于记录介质中的偏振干涉和光学各向异性，干涉光的偏振状态被三维调制。在各向异性光反应液晶复合材料中，偏振光的电场改变了指向矢的方向，形成了三维矢量全息图。从理论上揭示了合成的三维矢量全息图的形成机理和光学特性。
In this paper, we describe the principle of the three-dimensional vector holograms formed in anisotropic recording medium. The polarization states of the interference light are three-dimensionally modulated due to both the polarization interference and optical anisotropy in the recording medium. The electric field of the polarized light reorients the director and forms the three-dimensional vector hologram in anisotropic photoreactive liquid-crystal composites. The theoretical consideration reveals the formation mechanism and optical characteristics of the resultant three-dimensional vector holograms.
