Introduction to Multi-Conjugate Adaptive Optics systems
Introduction aux systèmes dʼoptique adaptative multi-conjuguée

The paper describes the basic concepts underlying the design of Multi-Conjugate Adaptive Optics systems. The paper takes into account mainly three papers. The first paper, published in 1988, is due to J. Beckers and it introduces the currently used multi-conjugation concept and quantifies the increase in FoV achieved applying this concept with respect to the single conjugate adaptive system. The second paper considered is due to M. Tallon and R. Foy. This paper, published in 1990, provides a quantitative method to estimate the 3D map of the atmospheric phase perturbation. This is the needed information to properly control the multi-conjugate system introduced by J. Beckers. Finally a third paper, published in 2000 and due to R. Ragazzoni et al. is considered, where the Layer Oriented scheme is described opening the multi-conjugate adaptive system field to natural guide stars. These three papers stimulated a lot of other contributions from several people and some of them are briefly discussed in the paper. To cite this article: S. Esposito, C. R. Physique 6 (2005).

Cet article présente les notions de base qui gouvernent le dimensionnement des systèmes dʼoptique adaptative multi-conjuguée [OAMC]. La synthèse présentée ici reprend principalement les résultats de trois articles. Le premier, publié en 1988 par J. Beckers, introduit le concept de multi-conjugaison and évalue le gain attendu en champ de vue par rapport à lʼoptique adaptative classique. Le deuxième article fondateur est celui de M. Tallon and R. Foy. Ce travail, publié en 1990, propose une méthode pour estimer quantitativement la carte 3D des perturbations de phase atmosphériques. Cette information est essentielle pour commander les systèmes multi-conjugués introduits par J. Beckers. Un troisième article majeur, publié en 2000 par R. Ragazzoni et al., décrit le principe de lʼanalyse de front dʼonde dite « Layer Oriented ». Cette technique permet dʼouvrir le domaine de lʼOAMC vers lʼutilisation dʼétoiles naturelles pour lʼanalyse de front dʼonde. Ces trois articles ont bien sûr stimulé un grand nombre dʼautres contributions émanant de divers instituts, lʼessentiel de ces travaux est discuté dans le texte qui suit. Pour citer cet article : S. Esposito, C. R. Physique 6 (2005).
