The goal of this study is to optimize pupil configurations for extended source imaging based on optical interferometry.
The motivation for this work comes from the observation of the Earth from a geostationary orbit (i.e. at a distance of km) with a resolution of 1 m. A simple calculus shows us that we would need a telescope having a diameter of approximately 20 m for an optical wavelength of nm. Needless to say such an instrument dimension is not adapted to the observation from space and the use of interferometric telescopes (Optical Aperture Synthesis, OAS) is to be considered in this case. We pursue a geometric approach  .
