我们考虑高孔径透镜通过具有不同折射率的两种介质之间的平面界面聚焦的问题。我们比较了最近发表的两种衍射理论和一种新的几何光学描述。两种衍射方法的轴向分布差异很小。基于几何光学的描述与衍射光学结果非常吻合。此外，还讨论了三维成像的一些含义。 (C) 1997 年美国光学学会。
We consider the problem of light focusing by a high-aperture lens through a plane interface between two media with different refractive indices. We compare two recently published diffraction theories and a new geometrical optics description. The two diffraction approaches exhibit axial distributions with little difference. The description based on geometrical optics is shown to agree well with the diffraction optics results. Also, some implications for three-dimensional imaging are discussed.
