Abstract
In order to solve the problem of image stable transmission in electromagnetic interference environment, an fiber bundles image transmission system with the ability of anti strong electromagnetic interference was designed and developed. By using ZEMAX, the front objective lens and the rear eyepiece lens in the image transmission system was designed, respectively. And according to the initial aberration distribution of the objective lens and eyepiece lens, the system aberration was further optimized by using the optimized function and various operation numbers. The optimized results show that, the MTF value of each field of view of the objective lens is greater than 0.85 at the spatial frequency of 38 lp/mm, and that of each field of view of the eyepiece lens is greater than 0.3 at the spatial frequency of 120 lp/mm, which has high imaging quality. According to the structural characteristics of the selected objective lens, eyepiece lens, fiber bundles and CCD, the coupling device of system connection is designed and manufactured, and the image transmission system is built for the image transmission experiment. By analyzing the imaging quality and influencing factors of the system, the image brightness is improved by using the Gamma algorithm, and the high-quality transmission image is obtained.
