Résumé de la justification scientifique
Wavefront sensing (WFS) and control are at the heart of Adaptive Optics (AO) and often dictate the performance. Various challenges are raised by the astrophysics programs like the characterization of exoplanets, the study of the stellar populations or the observation of the very first galaxies, for instance. For such programs, the requirements are to sense and control the wave-front in wide field of view, to combine natural and laser guide stars, to hunt for high sensitivity or high dynamics.
