摘要
利用微分几何方法研究光束传输。从黎曼三维流形的曲率出发，构造了一个复空间．它的流线能兼容几何光学与波动光学的信息。列举了复空间应用于光束传输的一些例子。
In this paper, the differential geometrical mothod is employed to study the propagation properities of light beams. Starting from the curvature of 3- dimensional Riemannian manifold, a new complex space which can contain the information of both geometrical optics and wave optics is built. Furthermore, some examples, in which the complex space is used to analyse beam propagation, are also given.
