In collaboration with P. Blanc and F. Falzon (Alcatel Alenia Space).
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 [42] .
