摘要
介绍了二种用于 ICF激光等离子体诊断的 X射线扫描式分幅技术的技术原理 ;分析了相关的性能参量 .借助于特别设计的扫描变象管进行了该技术的原理性实验 ,并利用计算机数字图象处理技术进行图象的重构 .实验获得了持续时间约 1 0 0 ps的发光过程的 1 6幅图象 ,曝光时间优于 1 0 ps.阴极上空间分辨率分别为 3 .5 lp/ mm.
Two kind of X ray streaking frame technique,the multi imaging and sampling image streak are introduced in principle.Theoretical analysis of both technique parameters,including the exposures time,framing ratio and spatial resolution is given.A specially designed streak image tube,together with an active passive mode locked YAG laser is used to make a preliminary proof of principle experiment for the technical,and by means of digital image processing the experiment result gives 16 frames with an exposure time of better than 8ps and spatial resolution of 3.5 1p/mm on and the photo cathode.
