Overview of multi-conjugate adaptive optics reconstructors
Clémentine Béchet
Multi-Conjugate Adaptive Optics (MCAO) systems aim at correcting for the atmospheric turbulence uniformly over wide-field observations. Compared to classical AO, this requires a to…
Optimization of adaptive optics correction during observations: Algorithms and system parameters identification in closed-loop
Clémentine Béchet, Michel Tallon, Éric Thiébaut
The adaptive optics (AO) on the European Extremely Large Telescope, as well as earlier pathfinders like the Adaptive Optics Facility, at the Very Large Telescope in 2014, will no l…
Upgrading SPHERE with the second stage AO system SAXO+: frequency-based data-driven controller for adaptive optics
Isaac Dinis, François Wildi, Damien Ségransan +22
This study introduces a novel frequency-based data-driven controller for adaptive optics, using power spectral density for optimization while ensuring stability criteria. It addres…
Towards a reliability assessment of the Cn2 and wind speed vertical profiles retrieved from GeMS
Benoit Neichel, Elena Masciadri, Andrés R. Guesalaga +2
The advent of a new generation of Adaptive Optics systems called Wide Field AO (WFAO) mark the beginning of a new era. By using multiple Guide Stars (GSs), either Laser Guide Stars…
Beam shaping for laser-based adaptive optics in astronomy
Clémentine Béchet, Andrés Guesalaga, Benoit Neichel +5
The availability and performance of laser-based adaptive optics (AO) systems are strongly dependent on the power and quality of the laser beam before being projected to the sky. Fr…
