自准直法测量薄透镜焦距时关于干扰像问题的分析

An Analysis of the Causes of Interferential Images Caused by Autocollimation's Gauging the Foci of Thin Lens

对自准值法测量时出现的几个干扰像进行分析、解释,着重分析了凸透镜也具有球面反射镜的性质,导出反射像和自准值法成像的关系,及若何判断干扰像。

This paper analyses and explains several interferential images arising from autocoUimation, and lays more emphasis on the analysis of the convex with identical property to a spherical reflector,introduces the relatios between reflection images and autoeollimation images, and expounds how to form to judgment about interferential images.
