Adaptive optics (AO), now installed on all the astronomical ground-based telescopes, make it possible to overcome the angular resolution limitations imposed by atmospheric turbulence. This article presents the state-of-the-art in the field of astrono

Today, adaptive optics (AO) is installed on all very large astronomical telescopes. It allows to overcome the limitation in angular resolution imposed on large ground-based telescopes by the atmospheric turbulence perturbations. This review paper pre

International audience; Laser guide star (LGS) wave-front sensing (LGSWFS) is a key element of tomographic adaptive optics system. However, when considering Extremely Large Telescope (ELT) scales, the LGS spot elongation becomes so large that it chal

Understanding the formation, the evolution and the diversity of extrasolar planets is an important purpose in modern astrophysics. More than 4,000 objects have been discovered since the first discovery of an exoplanet orbiting a solar-type star in 19

The astronomical community is paving the way for extremely large telescopes, with notably the ELT, a European telescope equipped with a 40-meter diameter primary mirror. This telescope will enable the study of fainter astrophysical objects with a bet

L’imagerie d’exoplanètes est limitée par deux obstacles intrinsèques : le faible écart angulaire entre planète et étoile, et le très faible flux lumineux en provenance de la planète par rapport à la lumière de l’étoile. Le premier ob
