摘　　要：利用手机和画图工具拍摄处理牛顿环干涉图像,通过显微镜视场直径求出画图工具中的像素和实际物理距离间的对应关系,进而求得牛顿环曲率半径.并把处理结果与常规用读数显微镜读数,逐差法处理数据的结果进行了对比.对比显示:牛顿环干涉实验的图像处理完全可以用手机和画图工具取代常规数据处理方法,避免了回程误差,得到了更好的实验结果.The interferometric images of Newton s ring is taken and processed by using mobile phone and drawing tool,and the corresponding relationship between the pixels in drawing tool and the actual physical distance is obtained through the field diameter of microscope,and then the radius of curvature of Newton s ring is obtained.The results are compared with those obtained by conventional reading of microscope and processing of successive difference method.The comparison shows that the mobile phone and drawing tool can completely replace the conventional data processing methods in the interference experiment of Newton s rings,and the hysteresis error is avoided,and better experimental results are obtained.
