摘　　要：为保证电气电子设备在辐射抗扰度试验中状态传输的稳定性,设计并实现了适用于试验环境的光纤束监控系统。系统主要由物镜、光纤束、转接镜和电荷耦合器件等组件构成。通过Zemax光学仿真软件,结合光纤束参数设计并优化了监控系统的物镜。设计结果表明:物镜在空间频率36 lp/mm处,各视场光学调制传递函数值大于0.8,像面大小与光纤束尺寸匹配,满足像方远心光路要求。对加工的物镜进行性能测试,表明其技术指标与理论设计比较相符。采用搭建的光纤束监控系统进行成像试验,并运用高斯滤波算法进行去像素化处理,提高了监控系统的视频传输质量,辐射抗扰度试验表明此系统具有良好的抗电磁干扰能力。A fiber bundle monitoring system appropriate for test conditions is devised and implemented to assure the stability of the state transfer of electrical and electronic equipment in radiated immunity tests.Components such as the objective lens,fiber bundles,conversion lens,and charge coupled devices compose the majority of the system.The monitoring system’s objective lens is designed and optimized using Zemax in conjunction with fiber bundle specifications.The design results show that the optical modulation transfer function value of each field of view of the objective lens is greater than 0.8 at the spatial frequency of 36 lp/mm,image area fits the fiber bundle size,and telecentric optical system in image space meets the criteria.The technical indicators of the processed objective lens are in line with the theoretical design,according to the performance test.The imaging experiment is conducted using the fiber bundle monitoring system,and the depixelation processing is achieved using the Gaussian filtering technique that improves the monitoring system’s video transmission quality,and the system’s anti-electromagnetic interference ability is demonstrated by the radiation immunity test.
