“…It is difficult to evaluate the modulation transfer function of fiber optic tapers. Although there were some research works with the MTF measuring methods and results for evaluating the quality of output images from the fiber optical plate [1,2] , the theoretical optic analysis and the methods for evaluating the modulation transfer function of fiber tapers are few. In this paper, the transmission characteristic of energy in the taper is analyzed firstly, and following the generalized definition of the modulation transfer function for sampled imaging system by Park et al [3,4] , the theoretical analysis and the methods for evaluating the modulation transfer function of fiber optic taper are put forward, also the mathematical model for fiber optic taper has been built.…”

Fiber optic taper has been used more and more widely as a relay optical component in the integrated taper assembly image intensified sensors for military and medical imaging application. In this paper, the transmission characteristic of energy in the taper is analyzed, and following the generalized definition of the modulation transfer function for sampled imaging system, a spatial averaged impulse response and a corresponding MTF component that are inherent in the sampling process of taper are deduced, and the mathematical model for evaluating the modulation transfer function of fiber optic taper is built. Finally, the dynamic and static modulation transfer function curves simulated by computer have been exhibited.
