摘要
在单轴晶体的光轴与入射面平行的情形下用费马原理计算非寻常光光线的折射角,然后就怎样定义非寻常光作些讨论,最后在单轴晶体的光轴任意取向的普遍情形下给出计算非寻常光光线折射方向的公式.
In the case of optical axis of uniaxial crystal being parallel with the incident plane, the angle of refraction of extraordinary ray are calculated by using Fermat's principle. The definition of extrodinary ray is discussed. And a group of calculation formulas of the refraction direction of extraordinary ray are given.
