摘要
设计了环聚焦光学系统,考虑反射镜表面粗糙度对聚焦性能的影响,利用"光线追踪法"建立了研究环形"点火"线形状、大小以及能流密度的数学模型。数值模拟结果表明:环聚焦模式对反射镜表面粗糙有一定的容忍度;同时在抗反射镜表面粗糙方面较点聚焦模式更加优越。
The ring focusing optical system was designed, also the effects of reflection mirror＇s surface coarseness were considered. Through ＂ray tracking method＂ the mathematic models of the ignition wire＇s shape, size and energy density were established. The results show that such a ring focusing system is of certain degree of roughness tolerance, and it is much better than spot focusing in the aspect of suffering reflection mirror＇s surface coarseness.
