摘要: 针对惯性约束聚变实验中多诊断系统在有限空间同时作业引发碰撞风险的问题,设计了基于碰撞目标检测和空间距离测算方法的空间干涉检测与预警系统,分析了真空靶室特定环境下不同实现方法的适用条件和可行性。实验室条件下模拟验证结果表明,基于结构光深度图像获取方法可获得较好的碰撞距离测量精度,在靶室半径探测距离内空间测距误差不大于3cm,为靶室空间干涉检测与预警提供了一种可行的解决方案。

Abstract: Aiming at the problem of collision risk caused by the simultaneous operation of multiple diagnostic systems in limited space in inertial confinement fusion (ICF) experiments, a space interference detection and early warning system is designed based on the methods of collision target detection and space distance measurement. The applicable conditions and feasibility of different realization methods are analyzed under the specific environment of the vacuum target chamber. The simulation results under the laboratory condition indicate that the depth sensing method based on structured light achieves high spatial distance measurement accuracy, and the distance error is no more than 3cm in the target chamber radius range, which provides a feasible solution for the detection and early warning of target chamber space interference in laser fusion experiments.
