基于MATLAB的牛顿环实际光路研究

Research on the Actual Optical Path of Newton Ring Based on MATLAB

牛顿环是光学中常见的一种光学实验,一般实验教材中的光路图是经过简化的。利用MATLAB的计算和图像处理功能研究了牛顿环的实际光路与简化光路之间的差别,发现实际实验时可以忽略这种误差,这对正确理解光学实验中的简化处理方法有一定意义。

Newton’s ring is a kind of optical experiment which is often seen in optics,but the optical path diagram in general textbooks is simplified.In this paper,the difference between the actual optical path and the simplified optical path of Newton’s ring is studied by using the calculation and image processing functions of MATLAB.It is found that this error can be ignored in the actual experiment,which is of great significance to correctly understand the simplified processing method in the optical experiment.
