A simplified method of ray tracing in cylindrical optical systems of arbitrary cross section is described. The technique involves the projection of a ray's path onto a cross-sectional plane perpendicular to the axis of translational symmetry. It is shown that this projected path obeys a generalized form of Snell's law, enabling application of conventional 2-D ray tracing methods. The approach is illustrated by demonstrating the optical characteristics of the recently patented prism light guide.
描述了一种在任意横截面的柱面光学系统中进行光线追迹的简化方法。该技术涉及将光线的路径投影到垂直于平移对称轴的横截面上。结果表明，这种投影路径遵循斯涅尔定律的广义形式，从而能够应用传统的二维光线追迹方法。通过展示最近获得专利的棱镜光导的光学特性来说明该方法。
