| Abstract: | 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 image,at the same time.the conjugate distance can also be observed by this method without the focal length. |
