摘要
借助等效光路,根据单个凸透镜的成像规律,研究并给出了自准直法测凸透镜焦距的光学系统的成像规律,并指出对在物平面中成清晰的像,除去一般教材中所讲述的情况之外,还应有另外情况。
According to the theory of equivalent light distance and law of image formation of single convex lens, the optical system was investigated for measuring the focal length of the convex lens in auto-collimation method and the law of image formation in such optical system was pointed out. There are other cases besides those mentioned in ordinary text.
