RAMA: A new agile AO bench for the telescope FEELINGS
Matteo Pasinetti, Rodrigo Andres Munoz Gomez, Benjamin Andres Gonzalez Barraza +16
The ground-based observation of extended objects such as satellites suffer from severe atmospheric propagation constraints. Specifically, high tracking velocities and low-elevation…
Modelling Fourier filtering wavefront sensors for PSD-based methods: the AOPERA tool
Romain Fétick, Vincent Chambouleyron, Lisa-Marie Mazzolo +6
Compensation of the atmospheric turbulence thanks to adaptive optics (AO) has now become commonly used for VLT or ELT class telescopes in order to retrieve a resolution close to th…
RISTRETTO: Assembly and Testing of the Seven-spaxel, High-resolution, Diffraction-limited Spectrograph
Leonie Hoerner, Bruno Chazelas, Nathanaël Restori +24
The RISTRETTO project aims at the direct detection of the reflected light of extra-solar planets to measure albedos and detect possible biosignatures, using the high-contrast / hig…
DM/WFS mis-registration tracking: Implementation and on-sky validation of SPRINT at LBT
Ben Buky, Cédric Taïssir Héritier, Fabio Rossi +7
The advent of telescopes with an integrated deformable mirror (DM) presents new challenges for adaptive optics (AO) systems. The alignment between the DM and wavefront sensor (WFS)…
HARMONI at ELT: Reoptimization of the NGSS natural guide star sensors system for MCAO compatibility
Kjetil Dohlen, David Le Mignant, Anne Bonnefoi +16
HARMONI is the first-light, adaptive optics assisted, near-IR integral field spectrograph for the ELT. It covers a spectral range from below 800nm to 2400nm with resolving powers f…
DD4AO control law for RISTRETTO: robustness, real-time performance, and on-sky validation with PAPYRUS
Isaac Dinis, Muskan Schinde, Nicolas Blind +11
This study presents DD4AO progress towards its implementation in the RISTRETTO instrument. DD4AO is a novel frequency-domain, data-driven controller for adaptive optics that levera…
Estimation of the laser guide star uplink tip-tilt using aperture size diversity
Pierre Jouve, Thierry Fusco, Carlos M. Correia +3
Laser guide star (LGS) adaptive optics cannot directly measure tip-tilt (TT), forcing reliance on natural guide stars and limiting sky coverage. We propose estimating the uplink TT…
On-sky demonstration of reinforcement learning for adaptive optics control
Jalo Nousiainen, Vincent Chambouleyron, Benoit Neichel +7
Reinforcement learning (RL)-based algorithms have recently emerged as a promising approach for adaptive optics (AO) control. In simulations and laboratory experiments, they have de…
