In a recent paper by Lin and Tsai [J. Opt. Soc. Am. A 29, 174 (2012)] there is presented a rather complicated method for derivation of the unit normal vectors of an aspherical surface given the knowledge of the unit directional vectors of the incoming and outgoing rays. In our comment we present a much simpler method that leads to compact equations suitable for practical implementation.
在林和蔡最近发表的一篇论文[《美国光学学会志A》29, 174 (2012)]中,提出了一种相当复杂的方法,用于在已知入射光线和出射光线的单位方向向量的情况下,推导非球面的单位法向量。在我们的评论中,我们提出了一种简单得多的方法,该方法能得出适用于实际应用的简洁方程。
