摘要
运用光纤导模（束缚模）理论和离散抽样理论分析了光纤象束象的质量，估算了决定波分复用象束系统象质的信息量Ｎ，Ｎ是到达象面的而且有与物场相位分布几乎相同的场模数，并估算了波分复用技术改善光纤象束系统象质的倍增率。
The imaging quality of a fiber bundle is analysed by using the theory of the well known guided mode and sampling theory. The information content N which determines the imaging quality of a wavelength multiplexing fiber bundle is evaluated, N is the number of modes that arrive at the image plane in almost the same phase relation as in the object. We also evaluate the improvement of the imaging quality of the fiber bundle system by using the wavelength multiplexing techniques.
