迈克耳逊干涉仪的干涉图样中干涉直条纹的分析与利用

Analysis and application of strainght interference fringe of Michelson interferometer

针对迈克尔逊干涉仪的干涉图样中干涉直条纹的相关问题做了论述。文中首先对迈克耳逊干涉仪的干涉条纹由圆变直这一矛盾转化的原因进行了分析 ,然后对在实验中干涉直条纹的应用做了举例说明 :利用直条纹可以使仪器调节得更好 ;利用直条纹可以确定等臂位置 ;利用直条纹也可以测钠光 D双线波长差。

The paper analyzed formation of Michelson interferometer's interference fringe from circle to straight,and it discussed the application of straight interference fringe in exeperiment and measurement.For example,using straight fringe are Very beneficial to regulation of instrument,to determination of level arm's position and to measurement of ware differece of Dinterfernce of equal inclination;straight interfernce fringe;optical path difference lines of sodium.
