Line-array fiber-optic image bundles on the contrast transfer function; 本文研究了线列光纤传像束的对比度调制传递函数。
Simulation results show that the MTF values of fiber-optic image bundles with random error is near the MTF values of ideal image bundles, so the influence of the fiber-optic error on the MTF is little. 结果显示,有随机误差的光纤束的平均MTF值分别分布于理想传像束平均MTF曲线附近,表明了光纤自身的误差对传像束的平均MTF影响不大;
