摘要
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5μm时,理论计算得到的夹角偏差为0.7492″,距离偏差为11.2083μm;当采用的激光跟踪仪测量误差为10μm时,夹角偏差为1.12″,距离偏差为18.2167μm。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。
