摘　　要：利用Matlab仿真牛顿环干涉,通过改变仿真程序中的相应参量得出牛顿环干涉圆环中心暗斑和对应级次条纹半径随介质膜折射率n的增大而减小,随平凸透镜的曲率半径R的增大而增大,随入射光波波长A的增大而增大,而且仿真结果与理论计算结果完全相吻合,是对传统的牛顿环干涉实验的完善和补充。Using Matlab simulated Newton's rings,it is found that the central dark spot and the corresponding secondary fringe radius of Newton's rings decrease with the increase of the refractive index n of the dielectric film,increase with the increase of the curvature radius R of the plano-convex Lens,and increase with the increase of the wavelength of the incident lightby changing the corresponding parameters in the simulation program.The simulation results are in good agreement with the theoretical results,which is a complement to our existing Newton's rings experiment.
