摘要
介绍了牛顿环曲率半径数据采集与处理的方法.该方法利用手机拍摄牛顿环干涉图像,使用Matlab对图像进行处理,利用视场直径计算出像素和实际物理距离的对应关系,进而完成对牛顿环曲率半径的测量.
A method for data acquisition and processing of curvature radius of Newton ring was introduced.This method used mobile phone to take Newton ring interference image,used Matlab to process the image,skillfully used the field of view diameter to calculate the corresponding relationship between the pixel and the actual physical distance,and then the radius of curvature of Newton ring was obtained.
