| 摘 要： | 本文通过实验和计算机模拟对偶氮苯聚合物光致双折射的写入、弛豫、擦写特性进行研究并对光致双折射的产生机制提出了一个新模型.指出对光致双折射有贡献的不仅是光致异构,分子链段的取向也有贡献,因而导致光致双折射有快和慢两个过程。

| Abstract: | Writing,relaxation and erasing processes in azobenzene polymers have been studied experimentally and theoretically.A new model of mechanism of photoinduced birefringence is presented.It is suggested that light induced isomerization and molecular chain orientation lead to the fast and slow processes of the photoinduced birefringence,respectively. |
