【摘要】 就光在晶面上的折射和光在内晶面的反射,在晶体光轴既不在入射面内又不垂直于入射面的一般情况下,求得了单轴晶体中非常光传播方向的两组普遍公式,指出除五种反射情况和四种折射情况非常光线在入射面内之外,其它情况均不在入射面内.更多还原

【Abstract】 When optic axis of crystal is neither in the incident plane nor perpendicular to it, the two general formulae for propagating direction of extraordinary light in the uniaxial crystal are obtained in the case that light is reflected at inner crystal plane and light is refracted when it passes through the Crystal, and this paper points out that all extraordinary rays do not lie in the incident plane except five kinds of reflection and four kinds of refraction.更多还原
