摘要
利用计算机层析技术,采用乘代数重建法(MART),编制出三维图像重建程序CT3D,通过五个方位对“星光Ⅱ”装置的惯性约束聚变靶进行X光针孔成像,重建出靶等离子体的三维图像,获得了较好的结果,表明该技术在惯性约束聚变实验中应用的可能性。
Abstract
A CT technique applied to ICF is developed and a three dimensional (3D) image reconstruction propram (CT3D) is performed. The 3D images of target′s plasma are reconstructed by using a multiplicatic algebraic reconstruction technique (MART) from five pinhole camera images obatined along different sight directions. The technique has been used to measure the three dimensional distribution of X ray of laser plasma experiments in the “Xingguang Ⅱ” facility, and the good results are obtained. It show that the CT technique can be applied to ICF experiments.
