双轴晶体内外偏振光传播方向的普遍计算

就任意方向的光线入射到任意取向的双轴晶体上的情况,求得了晶体内外偏振光传播方向的普遍计算公式,并就过渡到单轴晶体的情况,折射线在入射面内以及锥形折射情况作了研究。最后,就冰洲石、结晶硫的相应计算数据,画出了晶体转动时晶体中偏振光的方位曲线,加以讨论。本文结果为研究新的晶体光学元件、新的晶体常数测量方法提供了一个理论依据。

GENERAL CALCULATION FORTHE PROPAGATION DIRECTION OF POLARIZED LIGHT AT THE INNER AND EXTERNAL OF BIAXIAL CRYSTAL

General formulae for propagating directions of the polarized light at the inner and external of biaxial crystal are obtained in the case that ray along arbitrary direction is incident upon a crystal of arbitrary making direction. The transition from it to uniaxial crystal, refractive rays lying in the incident plane and cone refraction are discussed. At last, the corresponding numerical results are plotted in curvilineal diagrams for Iceland spar and crystal sulphur, they make the directions of the refractrive rays clear as the crystal rotates. These results provide an important basis for study of new crystal optical components and new measuring methods of crystal optical constants.
