晶体转动时非常光的轨迹

本文就光入射到单轴晶体的情况,求得了非常光线方向的普遍公式,并按冰洲石的相应数据画出了三视图,使得晶体转动时,非常光的轨迹明显可见。所得结果为测定晶片光学常数的新方法提供了可能性。

THE TRAJECTORY OF THE EXTRAORDINARY RAY AS THE CRYSTAL ROTATES

In this areticle, general formulae for the direction of the extraordinary ray are obtained in the case of light incident on uniaxial crystal, the corresponding data are plotted in three-view diagrams for Iceland spar, these make the trajectory of the extraordinary ray clear as the crystal rotates. The obtained results offer a possibility of developing new methods for determination of optical constants of crystals.
