摘要
开发了一个获得白光条纹的新实验.把劳埃镜干涉和光栅衍射结合起来,有可能使白光源产生的不同颜色的条纹彼此重合,从而能观察到清晰的黑白条纹.讨论了有关的实验原理、装置和方法,介绍了主要的实验关键并提供了相应的测量数据.
A new experiment of white light fringes has been developed. When Lloyd＇s mirror interference is combined with grating diffraction the fringes for different colors produced by white light source can be coincident, thus the white and black fringes will be observed. The theory, apparatus and method are introduced, and the key points of observation and measurement and data resuhs also are given.
