Given an arbitrary input wavefront, we derive the analytical refractive surface that refracts the wavefront into a single image point. The derivation of the surface is fully analytical without paraxial or numerical approximations. We evaluate the performance of the surface with several cases, and the results were as expected.

普通柱面

在给定任意输入波前的情况下，我们导出将波前折射为单个像点的分析折射面。表面的推导是完全分析的，没有近轴或数值近似。我们在几种情况下评估了表面的性能，结果与预期的一样。
