惠更斯作图求光在晶体中传播方向的解析法探讨

The Analysis of Huygens-diagraph in Searching for the Direction of Light Transmission in Crystal

对惠更斯作图求光在晶体中传播方向进行了解析法分析,得到了入射光经晶体表面折射后传播方向的解析表达式,证明了惠更斯作图求光在晶体中传播方向时,入射点及晶面上切线出发点的选取不影响最后光线方向的确定,并得出了光在单轴晶体中仍沿直线传播的结论。

After analysis of Huygensdiagraph in searching for the direction of light transmission in crystal,an analytical solution of the direction of light refraction via crystal surface is given.It is proven that the choice of entrance of light and the beginning of the tangent from crystal surface has no effect on resolving the final direction of light in crystal by Huygensdiagraph and a conclusion that light will still spread in line in singleaxiscrystal is drawn.
