【摘要】 主要介绍了背光成像实验样机的组成及工作原理,讨论了各光学部件的选择,在原理型样机建成后,获得了玻璃微球靶高质量的背光图像,通过对背光影像的光路图分析与测量(测量精度达到1μm),掌握了靶球DT冰层厚度的计算方法;初步建立了靶球二维内外表面粗糙度分析方法;通过设计模拟实验,获得了冰层在微球靶丸内均匀分布后清晰的背光影像。运用实验结果来模拟冷冻靶球DT燃料行为是非常重要的,它将为点火靶的设计和特殊表面粗糙度靶球的制备提供强大的支撑。更多还原

【Abstract】 The operating principle and component of the shadowgraph experimental station were introduced.The clear shadowgraph of target was gained after construction.Using this technique,the calculative method of DT ice thickness and the surface roughness analytic method of target were realized.Through design simulative experiment,the shadowgraph of DT ice was got.This simulative result will provide support for design of ignition target and fabrication of especial surface roughness target.更多还原
