Self-calibration of adaptive optics systems. Application to the THEMIS solar telescope
Clementine Bechet, Eric Thiebaut, Michel Tallon +3
The interaction matrix models the effects of deformable mirror (DM) commands as perceived by the wavefront sensor (WFS) and is the cornerstone of the Adaptive Optics (AO) control.…
SAXO+, the second-stage adaptive optics for SPHERE: NCPA compensation and dark-hole loop with a pyramid wavefront sensor
Johan Mazoyer, Charles Goulas, Raphaël Galicher +21
The SAXO+ upgrade of the VLT/SPHERE adaptive optics system introduces a second-stage near-infrared pyramid wavefront sensor to improve high-contrast imaging, making accurate calibr…
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…
