Optical gains measurement with a gain scheduling camera: On-sky demonstration with PAPYRUS and perspectives
A. Striffling, C. -T. Héritier, R. J. -L Fétick +4
Reaching the high angular resolution and contrast level desired for exoplanetary science requires us to equip large telescopes with extreme adaptive optics (XAO) systems to compens…
