Coordinate interrelation technique for three dimensional imaging in inertial confinement fusion

研究处理惯性约束聚变 ( ICF)中三维成像的各记录面间的关联定位问题。首先说明在 ICF中采用三维成像的必要性 ,然后对适用于 ICF的重建方法进行简要的描述 ,提出了通过光强重心进行坐标关联定位方法 ,定位精度可达到 10 μm,彻底解决了实验中的针孔相机需要精确关联定位的问题。

The coordinate interrelation technique for three dimensional imaging in inertial confinement fusion (ICF) is studied in this paper. First, it is confirmed that three dimensional imaging for ICF is necessary. Then the reconstruction methods suited for ICF are summarized. Finally, the coordinate interrelation technique through optical intensity center of optical intensity is put forward. The problem that accurate interrelation among pinhole cameras must be made is thorougghly solved.
