Abstract: The resolving power of optical fiber image transmission (OFIT) is studied, and a solution is provided in view of the problems coming up from that. Both the working principles and experimental outcome are introduced. The result shows that three-dimensional color image optical-fiber sensor which takes neutral photon as information-carrier instead of electron has the functions of real-time intussusception and transmission, as well as visualizing the colorful cubic target in time. Both its immunity to the effects of electromagnetic interference and capability of hiding itself are excellent. It is predicted that the system will become an important complement of the aeroplane-carried visual image electric system in the time of emergent power failure or in an electronic war.
