We describe a coronagraphic technique that can be used with an array of telescopes in space. It generalizes the use of Lyot's Masks and Roddier & Roddier's Phase Masks \cite{RR97} to an array of telescopes without the densification of the pupil recently proposed by \cite{LSB99} and \cite{GR99,GR00}. The proposed method consists of using an ensemble of masks set on the principal diffraction peaks of the point spread function. The best efficiency is obtained for a redundant configuration of the apertures. A linear array configuration is proposed for solving the problems of chromatism associated with phase mask coronagraphy and permits image reconstruction via tomographic techniques. A numerical simulation is made for a one-dimensional array of telescopes.
