• W2066223979 abstract "This paper proposes a design for a space borne demonstrator interferometer with imaging capabilities. This demonstrator would be a first step in the development of an operational astronomical instrument using aperture synthesis. Multiple aperture interferometry is a promising technique for high resolution imaging in space. Indeed the use of modular elements based on optical fibres represents an attractive low cost approach. The instrument is based on the use of independent triplets of telescope linked with optical fibres. For each triplet, only the phase closure of the system is measured. This does not require an accurate cophasing of the apertures and leads to realistic stability and control specifications. The complete instrument is then built by adding the desired number of such triplet modules. The detailed design of one module is described starting at level of the receiving telescopes down to the focal plane where the control of the stability of the optical path differences is performed as well as the scientific observations. The global operation of the system will also be described. We also briefly recall the technology validation activities which have shown on the ground the feasibility and performance of all components of such a systems as well as its end to end validation. Nous présentons ici le concept d'un imageur à synthèse d'ouverture pour application spatiale. L'interférométrie multitélescopes est une technique prometteuse pour l'imagerie haute résolution depuis l'espace. En effet, l'utilisation dans ce cadre d'éléments modulaires utilisant des fibres optiques permet une approche à bas coût comparée à l'utilisation de grands télescopes monolithiques. L'instrument présenté se compose de triplets de télescopes indépendants reliés par fibres. Pour chaque triplet on ne mesure que la clôture de phase. Ceci n'impose pas un cophasage extrême des télescopes et permet d'obtenir des spécifications réalistes pour la stabilité et le contrôle. L'instrument complet est obtenu en ajoutant le nombre requis de modules. Nous décrivons la conception détaillée d'un module depuis le télescope récepteur jusqu'au plan focal où s'effectue le cophasage et l'observation scientifique. Nous décrivons enfin l'opération globale du système complet." @default.
