本文介绍了飞行惯性聚变能（IFE）目标位置测量装置（PMU）的研制现状。采用Arago斑点现象的PMU设计测量精度小于1 μ m。通过采用发散的脉冲正交激光束照射，我们可以测量脉冲照射下的时间和目标位置。利用柱面透镜将二维的Arago光斑图像压缩成一维图像进行实时处理。PMU沿着飞行目标的注入路径设置。每个PMU中目标的局部位置被传输到控制器并进行分析以计算目标轨迹。提出了两种计算目标到达反应堆中心的时间和位置的方法。
We have reported the present status in the development of a position measurement unit (PMU) for a flying inertial fusion energy (IFE) target. The PMU, which uses Arago spot phenomena, is designed to have a measurement accuracy smaller than 1 μm. By employing divergent, pulsed orthogonal laser beam illumination, we can measure the time and the target position at the pulsed illumination. The two-dimensional Arago spot image is compressed into one-dimensional image by a cylindrical lens for real-time processing. The PMU are set along the injection path of the flying target. The local positions of the target in each PMU are transferred to the controller and analysed to calculate the target trajectory. Two methods are presented to calculate the arrival time and the arrival position of the target at the reactor centre.
