随着实验的进展，ICF研究中谱诊断要求X射线条纹相机具备直径50mm的探测面积。由于受场曲的限制，目前国内报导的性能较为优越的X射线条纹相机探测面积仅30mm，无法满足ICF研究所提出的大信息捕捉量要求。申请者提出采用同心球系统来设计大物面X射线条纹变像管。经过理论分析表明，该管型有效阴极直径可达50mm，受场曲影响较小，整个长度最少具备30 lp/mm 的理论极限空间分辨率，所能提供的信息量可达1500 线对；此外，为了校正大物面所引起的时间畸变，本项目将对时间畸变校正器件进行研究；同时，为了解决动态情况下图像的散焦问题，本项目亦将对所捕捉到的图像进行图像重建以提高条纹变像管的成像稳定性。

Along with the experiment progressed,spectrum diagnosis of ICF research required that the detection acrea diameter of X ray streak camera should be up to 50mm。However,due to the effcetion of the field curvature, the most superior X ray streak camerais in the domestic could provide detection area of only 30mm, which can not meet the reuqirements of ICF research with large information capture. The concentric sphere system is proposed to design the large format X ray streak image tube. The theoretical analysis shows that the tube could provide the photocathode with an effective diameter up to 50mm, which was less affected by the field curvature, the theoretical limiting resolution could be up to 30 lp/mm at least, the amount of information could be up to 1500 lines pairs. Moreover, in order to correct the time distortion caused by large format detection area, the project will focus on the development of time distortion correction device. Furthermore, in order to settle the problem of defocus image under the dynamic environment, this project will also focus on the image reconstruction to improve the stability of streak tube imaging.
