[LINC-NIRVANA : MCAO vers les télescopes extrêmement grands]
LINC-NIRVANA est un interféromètre de Fizeau (formation image) explorant la pleine résolution spatiale d'un télescope de classe de 23 m dans le faisceau combiné du LBT soutenu par le systeme optique adaptatif Multi-Conjugué (MCAO). Au moyen de cas de science, nous montrerons comment LINC-NIRVANA tire profit du MCAO, qui augmente la couverture de ciel de l'instrument et le champ visuel du traqueur de frange et de flexure. Nous présenterons le système de MCAO de LINC-NIRVANA en détail, qui dans une première étape sera installé avec deux miroirs deformable par bras et a la disposition dêtre prolongé avec un troisiéme miroir plus tard. Le système de MCAO met en application plusieurs concepts nouveau proposés pour les télescopes extrêmement grands, comme MCAO orienté par couche, Co-s'ajouter optique du guide tient le premier rôle ou champ visuel multiple senseur. LINC-NIRVANA les démontrera pour la premiére fois sur le ciel.
LINC-NIRVANA is a Fizeau (imaging) interferometer exploiting the full spatial resolution of a 23 m class telescope in the combined beam of the Large Binocular Telescope supported through Multi-Conjugated Adaptive Optics (MCAO). By means of science cases, we show how LINC-NIRVANA takes advantage of the MCAO, increasing the sky coverage of the instrument and the field of view for the Fringe and Flexure tracker. We introduce the MCAO system of LINC-NIRVANA in detail, which in a first step will be installed with two deformable mirrors per arm and has the provision to be upgraded with a third mirror. The MCAO system implements several novel concepts proposed for extremely large telescopes, such as layer oriented MCAO, optical co-adding of guide stars, or Multiple Field of View sensing. LINC-NIRVANA will demonstrate some of the concepts for the first time on sky.
