[Comparaison des ELTs, interferomètres et hypertélescopes pour l'imagerie des champs profonds et la coronographie]
On compare le potentiel de science des ELTs, interferomètres et hypertélescopes ayant la même surface collectrice. Des hypertélescopes ayant des centaines ou milliers de petites ouvertures surmontent le problème d'encombrement des champs qui affecte les interféromètres ayant peu d'ouvertures. Ils améliorent aussi le rapport signal/bruit comme
We compare the science potential of ELTs, interferometers and hypertelescopes having the same collecting area. Hypertelescopes with hundreds or thousands of small apertures overcome the ‘field crowding’ problem which interferometers have for aperture synthesis with few apertures. They also improve the signal/noise ratio as
