N2 - In order to solve the problem that the conventional optical system can not be placed apart in different areas, fiber bundle imaging optical system is needed. With a flexible fiber bundle, the detection target can be imaged onto the sensor. This paper uses a fiber bundle with φ8mm, length 50mm, resolution 30lp/mm, hexagonal arrangement, and 0.3 numerical aperture as the main component. The front objective and rear magnifying optical system of the optical system are designed. It provides a complete imaging solution for fiber bundle imaging. Through the glass fitting of the designed optical system, the results show that the field of view of the system can reach 35°, the numerical aperture of the front objective is 0.29, the numerical aperture of the rear optical system is 0.3ï1/4.the modular transfer function of the front objective lens can reach 0.38 in 30 lp/mm, and the modular transfer function of the rear magnifying optical system can reach 0.65 in 30 lp/mm,. It meets the requirements of field of view, numerical aperture matching, resolution and other parameters for fiber bundle imaging system. Furthermore, the selected glass are Chengdu Guangming's existing products, the system has high feasibility.
