| 摘 要： | 针对迈克耳孙干涉仪实验调节过程中经常会出现椭圆、双曲线等非圆形二次曲线条纹的现象,本文基于点光源条件下非定域干涉的原理,推导出了干涉条纹满足的曲线方程,分析了不同条件下干涉条纹的形状,发现观察屏上可呈现圆、椭圆、抛物线、双曲线和直线5种类型的干涉条纹.基于理论结果进行了数值模拟和实验验证,数值模拟结果和实验结果吻合较好.

| Abstract: | It is often found that there are non-circular quadratic fringes such as ellipse and hyperbola appeared in the experimental adjustment of Michelson interferometer.Aiming at this phenomena,this paper deduces the mathematical equation of the interference fringe based on the principle of non-local interference under the condition of point light source.On this basis,the shape of interference fringes under different conditions is analyzed.It is found that there are five kinds of line shapes of interference fringes can be acquired,they are circular,elliptic,parabolic,hyperbolic and straight.Based on the theoretical results,numerical simulation and experimental verification are carried out,and the numerical simulation results are in good agreement with the experimental results. |
