Abstract

A new formulation of the sampling theorem for circular apertures is proposed that uses a Dini series approach instead of a Fourier-Bessel one. The results obtained are especially convenient for the fast evaluation of pointspread functions: even the case of thin-ring aperture is not troublesome.

摘要

提出了一种用于圆形孔径的采样定理的新公式，该公式使用迪尼级数方法而非傅里叶 - 贝塞尔方法。所获得的结果对于点扩散函数的快速评估特别方便：即使是细环孔径的情况也不麻烦。
