Abstract

This paper describes a method of grinding a concave mirror to produce a prescribed aspheric contour. It also describes polishing and figuring procedures. The method was applied to produce a relay optical system that relayed the image of the planet Venus, at the same time correcting aberrations. The image relayed was formed by an uncorrected spherical primary telescope mirror. The relayed image was located at the center of curvature of the mirror. The image here was substantially free of spherical aberration.

摘要

本文描述了一种研磨凹面镜以产生规定非球面轮廓的方法。它还描述了抛光和修形程序。该方法被应用于制造一个中继光学系统，该系统中继金星的图像，同时校正像差。中继的图像由未校正的球面主望远镜镜形成。中继图像位于镜子的曲率中心。此处的图像基本没有球面像差。
