Design of Objective Lens and Realization of Monitoring System Based on Fiber Bundles
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.
