The European Southern Observatory (ESO) together with external research institutes have built a Multi-Conjugate Adaptive Optics (MCAO) Demonstrator (MAD) to perform wide field-of-view adaptive optics correction (2′ in K band). The aim of MAD is to demonstrate the on-sky feasibility of the MCAO technique and to evaluate its critical aspects in the framework of both the 2nd generation instrumentation for the Very Large Telescope (VLT) and the Overwhelmingly Large Telescope (OWL). The MAD module will be installed on the VLT to perform on-sky observations. MAD comprises two deformable mirrors and two different multi-reference wavefront sensors with natural guide stars. In this article we present the MAD design, some aspects of the MAD calibration and the first closed-loop results in the laboratory in Single Conjugated Adaptive Optics (SCAO) and Ground Layer Adaptive Optics (GLAO) configurations.
L'ESO ainsi que des instituts de recherche externes ont développé MAD (le Démonstrateur d'Optique Adaptative Multi-Conjuguée) pour effectuer la correction d'optique adaptative grand champ (2′ en bande K). Le but de MAD est de démontrer sur le ciel la faisabilité de la technique d'OAMC et d'évaluer ses points critiques pour l'instrumentation de 2eme génération pour le VLT et pour le télescope OWL. MAD sera installé au VLT pour effectuer des observations sur le ciel. MAD utilise deux miroirs deformables et deux senseurs de front d'onde multi-référence avec des étoiles-guide naturelles. Dans cet article nous présentons la conception du démonstrateur, quelques aspects de l'étalonnage de MAD et les premiers résultats en boucle fermée dans les configurations mono-conjugée (SCAO) et correction de la couche au sol (GLAO).
