| Abstract: | In this paper we have given a universal method for determining the focal length of optical systems and expounded the mechanism of circular moire fringes on circular concentric gratings. We have also given the quantity expression and the experimental results. The experimental results have demonstrated that this method is very simple and has a great application field. |
