Abstract

We present the principle and performances of a special kind of interferometric arrays that yields images of high dynamic range and large field. This array consists of a punched foil, in which numerous individual apertures form a pattern related to a Fresnel zone plate. We present the concept, theoretical results and simulations for exoplanets detection.
