摘要
本文针对凸透镜主点及物像平面难以精确定位的问题,提出了一种以理想光学系统的物像关系为理论基础,基于高斯公式,用CCD摄像机辅助的精确测量凸透镜焦距新方法,这种方法也可以在焦距未知的情况下,求共轭距。
In the paper,a new CCD - aided method to measure the focal length of convex lens is proposed in connection with the problem that it is hard to locate precisely the center of the center of the convex lens and the plane of object and image. This method is base on the Gauss formula and the relation between object and in：age, at the same time. the conjugate distance Can also be observed by this method without the focal length.
