| 摘 要： | 本文研究了全息存储实验中以波长532 nm的半导体激光器作为记录和读出光源,碱性品红作为光敏剂的丙烯酰胺基光致聚合物薄膜的光致光衍射现 象.它可以考虑为透过全息干涉条纹的原始入射光和反射光,与来自光聚物中未曝光的不均匀表面和内部的散射光四波混频的结果.根据简并四波混频理论中的位相匹配条件对双光束全息写入时产生的衍射光锥,以及单光束辐照复现时产生的衍射光锥现象分别做出了理论解释;并且利用全息散射理论结合三角学知识对入射光的入射角与衍射光锥的锥角的依赖关系进行了深入讨论.

| Abstract: | In the paper, a holographic storage experiment on laser optically induced light diffraction in acrylamide photopolymer thin film is reported, in which the semiconductor laser of 532nm is used as writing and reading light source, and fuchsin basic is used as sensibilizer. The appearance of diffraction rings can readily be explained as being holographic interference fringes formed by the original laser beam and light scattered from internal or surface inhomogeneities in the unexposed photopolymer. According to phase match condition of degenerate four-wave mixing theory, the diffraction cones of double laser beam holographic writing and single laser beam radiative reading are explained separately. The relationship between angle of incidence and diffraction cone angle is deeply studied by using holographic scattering theory with the help of trigonometric functions. |
