详细描述了神光 装置激光聚变物理实验靶瞄准定位系统的原理和结构, 提出了“空间坐标法”进行靶定位和靶瞄准, 利用“离焦定半径”完成了激光调焦。并给出系统综合实验的初步结果

This paper introduces the principle and structure of the Shenguang Ⅱ target pointing system used in inertial confinement fusion experiment. We use a space coordinate method to position and point the target and align the laser beam, and use an off-focus radius-finding technique to find the laser focus. The experimental results are given.
