| 针对激光惯性约束聚变（LICF）实验中诊断实验装置快速精确定位的迫切需求，提出了在LICF的实验场景下使用激光跟踪测量系统的快速定位瞄准方法。采用四路激光跟踪测量系统作为瞄准定位设备，构建了测量系统的数学模型，基于最小二乘法开展了系统瞄准定位精度的理论计算。当采用的激光跟踪仪测量误差为5 μm时，理论计算得到的夹角偏差为0.7492″，距离偏差为11.2083 μm；当采用的激光跟踪仪测量误差为10 μm时，夹角偏差为1.12″，距离偏差为18.2167 μm。理论计算结果表明，基于激光跟踪测量系统的瞄准方法，符合LICF中实验装置快速精准的定位需求，为将来在我国激光惯性约束聚变装置上使用激光跟踪测量系统作为瞄准定位设备提供了参考。 |

| In the laser inertial confinement fusion experiment, aiming at the urgent need for quick and accurate positioning of the diagnostic experiment equipments, the quick positioning and aiming method of using the laser tracking measurement system is proposed. The four-beam laser tracking measurement system is used as the aiming and positioning equipment, the mathematical model of the measurement system is developed, and the theoretical calculation of the aiming and positioning accuracy of the measurement system is carried out based on the least square method. When the measurement error of the laser trackers is 5 μm, the theoretical calculation angle error is 0.7492″, and the distance error is 11.2083 μm. When the measurement error is 10 μm, the angle error is 1.12″, and the distance error is 18.2167 μm. The theoretical calculation results indicate that the aiming method based on the laser tracking measurement system meets the quick and accurate positioning requirements of the experimental devices in the laser inertial confinement fusion. It provides theoretical guidance for using laser tracking measurement system as aiming and positioning equipment in China’s laser inertial confinement fusion device in the future. |
