用光致各向异性材料记录偏振全息光栅的分析

An Analysis of the Polarization Holographic Grating Recording With a Photoinduced Anisotropic Material

光致各向异性材料用偏振光曝光时可诱导出各向异性,作为偏振全息的记录介质用正交线偏振光和正交圆偏振光作参、物光波,用琼斯矢量表示它们的偏振态,讨论了平面全息光栅的曝光特性、再现光波的偏振特性及衍射效率。

Photoinduced anisotropic material, having induced anisotropy when exposed to polarized light, is used as a polarization holographic recording material. Its properties (diffraction efficiency, polarization state of the reconstructing wave, exposure characteristics of the planar holographic grating) are discussed, using Jones vectors for two types of polarization modulation-recording with two orthogonal linear polarized waves, and recording with two orthogonal circular polarized waves.
