摘要：
本文首先回顾了球对称介质中支配光线传播的基本求积公式。随后利用 Young-Kattawar 图对其解的若干定性性质进行了严谨讨论，该图可导出光线曲率的几何表述。文中深入研究了光学波导情形，分析了观察者相对于波导处于不同位置时的传递曲线。作者推导了关于其波长依赖性的新解析表达式，所得数值结果与计算机模拟相符。
英文摘要：
The fundamental quadrature governing light rays in a spherically symmetrical medium is first recalled. A rigorous discussion of some qualitative properties of its solutions follows, using the Young-Kattawar diagram which leads to a geometric formulation of the ray curvature. The case of an optical duct is deepened, analyzing transfer curves for different positions of the observer with respect to the duct. New analytical expressions for their wavelength dependence are derived, and their numerical consequences are coherent with computer simulations.
