| 摘 要： | 借助于数学工具和一种简单的实验装置,用直观的方法,使理论分析和图形相结合,从理论上解释了单轴晶光轴干涉图的成因,并给出了在白光照射下的干涉花样。搭建了实验光路,结果表明:若用单色光照射,干涉图为明暗相间圆环;若用白光照射,则为一个套一个的环状等色曲线。愈向视域边缘,干涉色级数愈高,等色曲线的数目愈多,密度愈大,表示晶体的双折射率愈大。实验结果与理论分析相吻合。

| Abstract: | The interference patterns of the uniaxial optical axis are explained by the mathematical tool and a simple experimental setup. The interference patterns of the white light are provided. The experimental light path is setup. The experiment results are given. The interference patterns are alternate bright and dark circles by using monochromatic light. The interference figures are the isochromatic ring curves by using white light. When the interference patterns approach the sight edge, the order of interference is higher, the numbers of the isochromatic curve are more, which expresses the crystal double refraction index is bigger. |
