摘要: 高能电子束进行韧质辐射靶标冲击试验时,靶标定位监测系统需要监测靶标重复定位位置的变化,记录靶标冲击试验时所产生的动态图像.首先,根据双目视觉原理,设计了靶标重复定位辅助系统,监测靶标空间位置的变化;然后,根据使用工况要求,设计了用于观测靶标冲击试验的ICCD镜头,实时记录靶标的动态图像;最后,通过搭建靶标监测系统测试平台,针对靶标重复定位辅助系统的定位精度和ICCD镜头的分辨率等参数进行了测试.试验结果表明,靶标重复定位辅助系统的空间位置定位精度为2%,ICCD镜头分辨率优于600 lp/mm.因此,该监测系统能够满足高能电子束试验中的靶标精确定位和靶标动态图像的使用要求.Abstract: In high-energetic particle burst experiment, target monitoring system has the function of bremsstrahlung conversion target filament accurate positioning, and acquiring the dynamic image of bremsstrahlung conversion target filament in experiment. First, an accurate positioning system of the micro target filament was designed to monitor the original position, according to the binocular stereo vision theory. Then, ICCD camera lens was developed to record the dynamic image collision experiment in working conditions. Finally, an experiment platform simulating the real using condition was established to test the positioning accuracy error of this system and high optical resolution. The experiment results indicate that the accuracy error of this positioning system is 2%, and the optical resolution of ICCD camera lens is better than 600 lp/mm, which illustrate that this built positioning system can reach the goal of the accurate positioning of the bremsstrahlung conversion target filament in the high-energetic particle burst experiments, and ICCD camera lens can meet the need of high-energetic particle burst experiment.
