A flexible adaptive optics concept for general purpose high angular resolution science on the DAG 4m telescope

Jolissaint, Laurent; Bouxin, Audrey; Gokay, Ulas S.; Keskin, Onur; Rigaut, Francois; Yesilyaprak, Cahit


Thanks to the availability of high actuator density deformable mirrors (ALPAO 468 DM), the high versatility of the pyramid wavefront sensor and above all, the venue of essentially no noise EMCCD detectors, it becomes possible to fully adapt the degree of correction of an adaptive optics system for a given guide star brightness and atmospheric condition. Indeed, when the conditions are very good, the high actuator density of the DM allows to reach a high Strehl by using all the modes, and when...[Show more]
