牛顿环实验中正确测量暗环直径的理论依据

The theoretical basis of correct measurement for the diameters of dake rings in the experiment of Newton’s rings

针对在"用牛顿环测透镜的曲率半径"实验中暗环条纹直径正确测量的问题,通过光学理论分析得出应选取暗环两侧的条纹外边缘之间距作为暗环直径的结论。

In this paper,the optical theory of measurement for the diameters of dake rings in the experiment of Newton’s rings is analyzed,and the conclusion of the diameter of dake ring is a distance between outer edges of its two sides is also presented.
