本論文是以脈衝雷射作為寫入光且氦氖雷射作為探測光，去瞭解液晶材料的相態其中有近晶C、相近晶A、向列相、各向同性，藉由改變溫度以及探測光的偏振方向，來研究摻雜偶氮染料的雷射誘發全像光柵.

In this study, the pulse laser was used as writing beam, and He-Ne laser as the probe beam. The liquid-crystal has several mesomorphic phase: Smectic C, Smectic A, Nematic and Isotropic. The laser-induced holographic gratings in the azo-dye-doped liquid crystals have been investigated by changing the temperature, and the polarization of the probe beam.
