Achieving the Ultimate Limit of Two Point Resolution by Computational Imaging

Not Accessible

Your library or personal account may give you access

Abstract

The smallest estimable separation of two incoherent monochromatic point sources is considered to be a fundamental measure of imaging resolution. We extend the fundamental limit of two-point source resolution of a Gaussian aperture to an arbitrary aperture and propose a single-mode measurement that approaches this limit in the sub-diffraction regime.
