| 摘 要： | 本文介绍如何通过计算机光线追迹模拟瑞奇-康芒(Ritchey-Common)检验,找出被检平面镜面形误差与检验系统波象差之间的相互关系,建立一组影响函数。根据分别在两个不同瑞奇角下求得的影响函数和测出的系统波象差,通过最小二乘法求解一组过定线性方程,即可求得被检平面镜的面形误差。文中给出了一块直径为1m的高精度平面镜的检测实例。

| Abstract: | The procedure of how to simulate the Ritchey-Common test to derive the relationships between the figure errors of an optical flat and the wave-front aberrations, and to construct a set of influnce functions by ray-tracing program, is here presented. Figure errors of the flat can be extracted from a set of over defined linear equations with the aid of least squares, using the influnce functions and the measured wave-front aberrations for two different Ritchey angles. A test example on a high quality flat 1 meter in diameter is shown. |
