has gloss | eng: An astronomical interferometer is an array of telescopes or mirror segments acting together to probe structures with higher resolution by means of interferometry. Astronomical interferometers are widely used for optical astronomy, infrared astronomy, submillimetre astronomy and radio astronomy. Aperture synthesis can be used to perform high-resolution imaging using astronomical interferometers. Very Long Baseline Interferometry uses a technique related to the closure phase to combine telescopes separated by thousands of kilometers to form a radio interferometer with the resolution which would be given by a single dish which was thousands of kilometers in diameter. At optical wavelengths, aperture synthesis allows the atmospheric seeing resolution limit to be overcome, allowing the angular resolution to reach the diffraction-limit of the array. |

has gloss | fra: Lhypertélescope est un interféromètre où lon recombine simultanément tous les télescopes/miroirs afin dobtenir une image directe lumineuse des objets astrophysiques observés. De façon plus formelle, il sagit dune méthode de recombinaison optique qui permet dobtenir une image astronomique directe à très haute résolution angulaire avec un interféromètre. Ainsi, le recombineur d'un hypertélescope fonctionne selon le principe de la pupille densifiée. |
