| 摘 要： | 改进的斑点法测量自聚焦透镜的主要参数是利用直径不同的近轴平行光束垂直入射到自聚焦透镜端面，在出射端面测量光束光斑大小之差，从而确定了自聚焦透镜的周期长度ｐ，焦距ｆ以及中心折射率ｎｏ和分布常数Ａ。本文报导了改进的斑点法测量原理及测量方法，并对测试结果作了比较。

| Abstract: | The modified spot way is adopted to measure the optical parameters of self colens.Parallel paraxial rays with different diameters are incident on the end surface of self co lens. It is by measuring the difference between diameters of output rays that we can determine the periodic length P,focal length f,central reflection index no, and distribution coefficient Ao.We report the principle of the modified spot way and its application. Theeyaluation of experimental results is also provided. |
