为了缩短惯性约束聚变(ICF)激光装置在靶场区光束引导的总时间为基于光束引导传感器固定子区划分的光束引导方法,提供了引导路径的一种优化方法。通过优化预备子区中心到目标子区中心的角度,最小化对引导总时间有贡献的投射镜的角位移量的总和。以终端光学组件的一种布置为研究对象,以引导目标点为靶室中心的情况为例,介绍了引导路径的优化过程。引导总时间的估计表明,与普通的串行光束引导方法相比,该方法可以很大程度上缩短光束引导的总时间。当预备子区中心与目标子区中心之间的距离为1 mm时,引导总时间可以缩短为采用普通串行引导方法时的0.518倍。
In order to shorten the total time that the inertial confinement fusion (ICF) laser device directs the beam in the shooting range as a beam steering method based on the fixed subarea of the beam guidance sensor, an optimized method for guiding the path is provided. By optimizing the angle of the preparation subzone center to the center of the target subzone, the sum of the angular displacement of the projection lens contributing to the total guidance time is minimized. Taking an arrangement of terminal optical components as the research object, taking the case that the target point is the center of the target chamber as an example, the optimization process of the guiding path is introduced. The estimation of the total lead time shows that this method can greatly reduce the total time of beam steering as compared to a conventional serial beam steering method. When the distance between the preparation subzone center and the target subzone center is 1 mm, the total guidance time can be shortened to 0.518 times when using the common serial guidance method.
