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…
Improved prior for adaptive optics point spread function estimation from science images: Application for deconvolution
A. Lau, R. JL. Fétick, B. Neichel +2
Access to knowledge of the point spread function (PSF) of adaptive optics(AO)-assisted observations is still a major limitation when processing AO data. This limitation is particul…
Blind deconvolution in astronomy with adaptive optics: the parametric marginal approach
Romain Fétick, Laurent Mugnier, Thierry Fusco +1
One of the major limitations of adaptive optics (AO) corrected image post-processing is the lack of knowledge on the system point spread function (PSF). The PSF is not always avail…
Physics-based model of the adaptive-optics corrected point-spread-function
Romain Fétick, Thierry Fusco, Benoit Neichel +8
Context. Adaptive optics (AO) systems greatly increase the resolution of large telescopes, but produce complex point spread function (PSF) shapes, varying in time and across the fi…
