Thanks to the atmosphericturbulence correction system NAOS, developed under ONERA management, the discoveries of the VLT have been exceptional: planetary details of our solar system, the first images of an exoplanet, the revelation of a super massive black hole in our galaxy, etc.
Atmosphericturbulence is an issue for air transport comfort and safety... Onera is a partner of Thales for the system modeling aspects and a partner of CNRS for atmosphericturbulence data acquisition and modeling
Real-time correction of images using the deformable mirror, which corrects atmosphericturbulence effects over 1300 times per second with nanometric accuracy, made it possible, among other technological feats, to make this discovery and to access all of these data on this exoplanet. This system, which has become an integral part of Sphere, is based on ONERA's know-how in adaptive optics
