Field-resolution ratio in multi-aperture imaging

Abstract
This paper presents a theoretical limit to the field/resolution ratio for the
imaging mode of aperture synthesis interferometers. This limit is a function of
both the number of apertures in the interferometric array and the dynamic range of
the visibility and phase data. It does not depend on the optical setup of
the instrument. This work is based on an application of the theory of information.
