摘要
本文用光线光学的方法导出了反射式施密特望远镜校正板的面形方程,分析了子午面内视场光束引起的初级球差,得出应使象面作倾斜调焦以改善象质的结论。最后通过实例计算了一个系统的空间光线成象点图及倾斜调焦后的改善情况。
In this paper the equations of the reflecting Schmidt telescope corrector are derived by the ray optics method. The primary spherical aberration of field beams is analysed, and the conclu- sion is that the image plane should be tilted in order to reduce the size of image diffusion. Finally, the image spot-diagrams of beams both in meridional and sagittal planes with different tilts are calculated by ray tracing.
