单轴晶体内表面入射o光线的双反射

Reflection of the Incidence O-Ray on the Internal Boundary Surface of Uniaxial Crystal

基于光线遵从的Fermat原理 ,从几何学的角度讨论和分析了在单轴晶体中入射的O光线在界面上的双反射 ,得到了确定光线反射方向的一般公式 ,并对几种特殊情况进行了讨论。指出了上述结果推得的确定反射光波法线方向的公式 ,与由电磁波的边界条件所得结果是一致的。

On the basis of the Fermat’s principle of the anisotropic medium , the reflection of the incidence o-ray is discussed and analyzed on the internal boundary surface of the uniaxial crystal. The reflection formulas of the e-ray reflected is derived in any direction of optical axis of the uniaxial crystal, and some special cases are discussed . It is also pointed out that the result is the same as those being calculated on basis on the boundary condition of the electromagnetc wave.
