The next decade will see the first light of the new Extremely Large Telescopes (ELTs). Those giant telescopes with an aperture for its primary mirror from 25 meters up to 40 meters across, will address fundamental questions of modern astrophysics from exoplanet direct imaging to the study of the first galaxies.Their large diameter, increases both their sensitivity and their angular resolution, which is the ability to discern the very small details. However, the angular resolution of all sizes ground-based telescope is always strongly limited by the atmospheric turbulence. These movements of air layers with different temperatures induce fluctuation in the optical index and alter the shape of the incident wavefront.To tackle this problem and ...
