本論文主要是利用兩道相干激發光束（氬離子雷射，波長為514.5nm）產生干涉場，此場調制液晶聚合物混合薄膜內部之折射率後將使薄膜形成全像光柵，藉由提出光柵形成動態模型來了解偵測光(Probe beam)（氦氖雷射，波長為632.8nm）偵測樣品之一階繞射動態變化效應之根本機制。

We study the dynamical behavior of the holographic grating formed in polymer-dispersed liquid crystal ( PDLC ) films. The grating is written by two coherent Ar+ laser ( l=514.5nm ) , while probed by a He-Ne laser ( l=632.8nm ).
