共轴球面光学系统的节点及其特点

The Nodes and Their Characteristics in Coaxial Spherical Optical System

文章采用几何光学系统的物象公式,节点的定义和位置坐标公式,求解出单球面(含折射面和反射面)、双球面、薄透镜和由多个双球面构成的共轴光学系统的节点坐标,然后进一步分析比较各自的几何特点和光学特点,得出了一些很有用的结论。

In this paper, first, the nodes＇ coordinates in coaxial spherical optical systems which include single and double refraction spherical surface, single reflection spherical surface, thin convex lens, and multi - double spherical optical system, are worked out according to the formula about object and image and the nodes＇ definition. Second, with being analyzed of their geometrical and optical characteristics, some useful conclusions on the computation and looking for the nodes in experiment are summed up.
