title: Sampling theorem for rotationally symmetric systems based on Dini expansion.
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.
