Based on diffraction theory, this paper theoretically demonstrates improvements in axial resolution in confocal microscopy with fan-shaped apertures. It provides the optimal geometric parameters of the fan-shaped pupils to give the maximum axial resolution for a given pinhole size. To fully understand the overall performance, the signal-to-background ratio and the signal level with regard to the geometric parameters are discussed.
基于衍射理论，本文从理论上论证了扇形孔径共聚焦显微镜轴向分辨率的提高。它给出了扇形光瞳的最佳几何参数，以便在给定针孔尺寸下获得最大轴向分辨率。为了全面了解整体性能，还讨论了与几何参数相关的信噪比和信号水平。
