中文摘要
本論文採用雷射誘發全像光柵技術,藉由改變溫度來研究多態液晶摻雜偶氮染料樣品之動態強度光柵的形成機制。本實驗所使用的液晶材料的相態歷經近晶C相、近晶A相、向列相及各方均向,我們將探討探測光偏振方向在多相態液晶中對一階繞射現象之影響。
Abstract
The laser-induced holographic grating technique was employed to study the dynamic of the intensity grating formation in the azo-dye doped liquid crystals. The liquid crystal material in this study has several mesomorphic phases: Smectic C, Smectic A, Nematic and Isotropic. The first order of diffraction in the mesomorphic phases have been investigated by changing the polarizations of the probe beam.
