| 摘 要： | 测量长距离反射镜的曲率半径，不论是在验证近轴光线球面镜的成象公式还是在实践上都有很重要的意义。但是如果反射镜表面的曲率半径Ｒ＞５ｍ时，验证和测量都是相当复杂的问题。本文给出了一种很简便的测定Ｒ的方法，在曲率半径是１０ｍ左右时的测量误差是１％。

| Abstract: | The measurement of the radius of curvature of long focus reflector is of great significance nomatter whether it is in verifying the formuLla of imagery of para-ctal ray spherical mirror or in practicalapplication. However, if the radius of eurvature of the refilector surface is R > 5m, the verification or masurement is a rather complicated problem. This paper presents a quite simple way for measuring R. Whenthe radius of curvaturre is some 10m, the measuring error is 1 percent. |
