X光环孔编码成像技术研究

着眼于惯性约束聚变实验研究中的应用，对X光环孔编码成像技术进行了研究。利用数值模拟的手段，分析了环孔的自相关函数及其对环孔编码成像技术图像重建的影响，对不同的图像重建技术进行了初步比较。基于星光II实验装置，利用自行研制的X光环孔编码成像系统进行了激光等离子体X光环孔编码成像技术的演示实验，获得了满意结果。

Investigation of X ray ring aperture coded imaging technique

Investigation of X ray ring aperture coded imaging technique is performed aimed at the application of inertial confinement fusion research. The auto correlations function of a ring aperture is calculated numerically. The effect of the function on the image reconstruction in the coded imaging is analyzed. A primary comparison of different image reconstruction treatment is gaven. Ring aperture coded imaging could have a better spatial resolution than the width of the ring with deconvolution reconstruction technique. Experimental demonstration of laser plasma X ray ring aperture coded imaging is performed on the Xingguang II facility and content results are obtained.
