本文介绍了最近发展起来的经典离轴反射望远镜和成像系统几何像差理论的基本概念和基本结果。结果表明，通过消除由非对称几何结构引起的主像差（线象散），经典的离轴反射式望远镜可以设计成具有实际上轴对称的光学特性。本文提出了一个简单的消除线象散的封闭方程。此外，为了展示如何发展的像差理论可以应用到当前和未来的望远镜，几个离轴反射望远镜和成像系统的设计和分析。
The basic concept and fundamental result of a recently developed geometric aberration theory for classical off-axis reflecting telescopes and imaging systems are presented. It is shown that a classical off-axis reflecting telescope can be designed to have practically axially-symmetric optical property by eliminating the dominant aberration (linear astigmatism) caused by the asymmetric geometry. A simple closed-form equation for elimination of linear astigmatism is presented. Also, to show how the developed aberration theory can be applied to current and future telescopes, several off-axis reflecting telescopes and imaging systems are designed and analyzed.
