Les développements récents visent d'une part à augmenter la qualité de la correction afin d'imager des exoplanètes, et d'autre part à étendre le champ corrigeable. [...] l'OA [optique adaptative] peut souffrir de deux limitations importantes dues à la luminosité limitée des sources astronomiques et aux effets d'anisoplanétisme [...] En effet, l'AFO [analyseur de front d'onde] doit détecter une certaine quantité de photons pour effectuer correctement la mesure. Il faut donc disposer d'une source suffisamment brillante, dite étoile guide. Souvent l'objet observé est trop faiblement lumineux, il faut alors chercher une étoile brillante environnante mais hélas à proximité immédiate à cause de l'anisoplanétisme, réduisant sérieusement la couverture du ciel. 2, record 1, French, - %C3%A9toile%20guide
