摘要: 利用二轴晶的光波面,对光轴与光线轴的关系进行了研究.计算出了光轴与光线轴夹角的具体表达式,把它应用到黄玉与堇青石中,发现夹角远小于1度.这给光学器件的设计提供了重要的依据.最后对一轴晶进行了讨论,结果表明此时光轴方向与光线轴方向一致.

Abstract: The relation of ray axis and optical axis is discussed by using the optical wave camber of biaxial crystal. The mathematical expression of included angle between ray axis and optical axis is also given. The result shows that the included angle is much less than 1° in two biaxial crystals (topaz and cordierite). This is important for the design of the optical devices. It indicates that the direction of ray axis and optical axis is identical by discussing the uniaxial crystal at last.
