Optimizing Fourier-Filtering WFS to reach sensitivity close to the fundamental limit
Vincent Chambouleyron, Olivier Fauvarque, Cédric Plantet +5
To reach the full potential of the new generation of ground based telescopes, an extremely fine adjustment of the phase is required. Wavefront control and correction before detecti…
PSF nowcast using PASSATA simulations -- Towards a PSF forecast
A. Turchi, G. Agapito, E. Masciadri +8
Characterizing the PSF of adaptive optics instruments is of paramount importance both for instrument design and observation planning/optimization. Simulation software, such as PASS…
Three-sided pyramid wavefront sensor. II. Preliminary demonstration on the new CACTI testbed
Lauren Schatz, Johanan Codona, Joseph D. Long +17
The next generation of giant ground and space telescopes will have the light-collecting power to detect and characterize potentially habitable terrestrial exoplanets using high-con…
Adapting the pyramid wavefront sensor for pupil fragmentation of the ELT class telescopes
Nicolas Levraud, Vincent Chambouleyron, Olivier Fauvarque +8
The next generation of Extremely Large Telescope (24 to 39m diameter) will suffer from the so-called "pupil fragmentation" problem. Due to their pupil shape complexity (segmentatio…
Performance characterization and near-realtime monitoring of MUSE adaptive optics modes at Paranal
T. Wevers, F. J. Selman, A. Reyes +13
The Multi Unit Spectroscopic Explorer (MUSE) is an integral field spectrograph on the Very Large Telescope Unit Telescope 4, capable of laser guide star assisted and tomographic ad…
Super-resolution wavefront reconstruction
Sylvain Oberti, Carlos Correia, Thierry Fusco +2
Super-Resolution (SR) is a technique that seeks to upscale the resolution of a set of measured signals. SR retrieves higher-frequency signal content by combining multiple lower res…
