针对磁驱动飞片的物理过程，设计了显微装置和激光阴影照明装置。结合超高速转镜式扫描相机，利用串联式光电开关避免相机像面重复曝光，有效地解决了飞片被碰撞过程中严重影响测试结果的自发强光现象，获得了磁驱动加载下飞片运动过程清晰的一维扫描试验图像。图像分析数据表明，在充电电压为60～64 kV时，可将尺寸为8 mm×6 mm×0.7/0.9 mm的Ly12铝飞片发射至9～14 km/s的超高速度，且飞片运动速度与充电电压和飞片厚度有关。该项工作为磁驱动飞片运动过程的研究提供了一种重要的测试手段，其测试方法也适用于其它产生强烈杂光的高速碰撞的测试研究。

According to the physical process of flyer plates driven by magnetic fields, an ultra-high speed photographic system including an ultra-high speed rotating mirror streak camera, a micrographic lens suitable for the optical system of the camera and a continuous laser source was developed. An electric-optic switch in series was used to avoid the repetitious exposure on imaging plate of the camera, by which the intense light produced in the course of collision was bated and 1D clear-cut streak images of flyer plates driven by an electric gun were obtained firstly at home. Experimental results show that Ly12 flyer plates with the size of 8 mm×6 mm×0.7/0.9 mm can be accelerated in 9-14 km/s within 1.8 μs when the charge voltages of flyer plate reach in 60-64 kV. The results demonstrate that the charged voltages and the thicknesses of flyer plates have great effect on the movement velocities of the flyer plates. The present work will be helpful for researching flyer velocity and can provide important data for the development of electric guns.
