中文摘要：

研究一种新型的并列式的高密度存储材料ADPA-PVK-PBA-TNF聚合物薄膜.在非吸收区用光抽运测试法研究了薄膜光致双折射,获得光致双折射变化值Δn=1.3×10-3,分析了该聚合物薄膜光致取向增强的物理和化学机理.探讨了抽运光对光致双折射的增强和抑制效应.在此基础上初步实现了多重角度复用信息存储、获得了较为清晰的全息存储图像.并讨论了图象存储的增强/抑制效应,利用这种效应可对存储图像处理或删除.

英文摘要：

A novel optical high-density storage material ADPA-PVK-PBA-TNF polymer film was reported.In the nonresonant absorption of sample,we tested and investigated its photo-induced birefringence and obtained the value Δn = 1.3 × 10-3.We analyzed the physico-chemiscal mechanism of orientation-enhancement and discussed the enhancing /restraining effects of photo-induced birefringence in the film.On this basis,multiple angles storage were achieved and clear holographic storage images were gained.The enhancing /restraining effect of image storage was also discussed.And with the help of this effect one can process and remove storage images.
