In many precision physics experiments, due to special environmental requirements, the experiment must be carried out in a closed container, which makes it impossible to directly perform ultra-high-speed imaging measurements on a small field of view. In order to meet this demand, based on the optical fiber image bundle, this paper carried out the optical and mechanical design of the endoscopic lens, the sealed adapter lens and the ultra-high-speed camera coupling objective lens, and finally transmitted the target image to the self-developed ultra-high-speed optic-electronic framing camera. So as to realize ultra-high-speed imaging of small field of view. The resolution test and dynamic experimental verification of the designed system have been carried out. The test result shows that the surface system can achieve the high-quality imaging requirements of the small field of view on the target surface. At present, this system has been applied in related physical experiment test research.
