Solutions for tracing the extraordinary ray through a uniaxial nonabsorbing birefringent crystal are presented in a simple and explicit form that is directly amenable for computer programming. The general case in which the incident ray, the optic axis, and the exit surface have arbitrary orientation with respect to the entrance surface is treated. Solutions for the extraordinary wave vector within the crystal are also given.
以一种简单且明确的形式给出了用于追踪非常光线通过单轴非吸收性双折射晶体的解，这种形式可直接用于计算机编程。处理了入射光线、光轴和出射面相对于入射面具有任意取向的一般情况。还给出了晶体内非常波矢的解。
