摘　　要：研制了一种新的钛酸铅 聚醚醚酮 (PT PEK c)纳米晶聚合物复合薄膜 ,用视频摄像技术准确、实时地分析了这种复合薄膜的传输损耗。该方法包括一架高分辨率的数码相机和相应的数据处理软件 ,以及棱镜耦合系统 ,其测量范围为 0 5～ 10 0dB/cm ,用这种方法测得PT PEK c纳米晶聚合物复合薄膜在 6 33nm处的传输损耗为 3 0 9dB/cm。A kind of novel nano-crystal and polymer complex thin film PT-PEK-c was fabricated. The transmission loss of the complex thin film was measured accurately and real-timely using photographic technique. The method involves a digital camera that has good spatial resolution and corresponding data processing software, the prism-coupling system as well. It can be used over a wide range of loss values from 0.5dB/cm to the order of 100 dB/cm. The transmission loss of nano-crystal and polymer complex thin film PT-PEK-c at 633 nm is measured to be 3.09 dB/cm.
