| 摘 要： | 对惯性约束聚变靶丸芯部诊断的测量仪器要求具有10ps的时间分辨,为了满足此要求,采用多针孔线阵配X光条纹相机,由多个针孔的一维条纹图象的数据,利用图象处理技术重建出二维图象,由此获得一项高时间分辨的二维空间成象技术(MIXS).此技术利用现有的设备获得比X光分幅相机高得多的时间分辨的二维图象.利用此技术可获得研究激光聚变内爆过程所需的时空图象,并可以对压缩过程的对称性进行研究.

| Abstract: | A pinhole linear array was coupled to X ray streak camera,and two dimensional images were reconstructed by handled the multi pinhole streaked images data.Then a X ray two dimensional imaging technique with high time resolution was obtained (MIXS).Its time resolution is higher than X ray gated frameing camera.Using this technique,the time space images for core plasmas of laser implosion can be measured and symmetry during the implosion investigated. |
