On-sky results from REDWOODS, a platform at Lick/ShaneAO for testing second stage AO technologies
Benjamin L. Gerard, Dominic F. Sanchez, Aditya R. Sengupta +11
REDWOODS is a new sub-testbed within the Shane Adaptive Optics (AO) system at Lick observatory, developed to test second stage AO wavefront sensing and control technologies, includ…
DD4AO control law for RISTRETTO: robustness, real-time performance, and on-sky validation with PAPYRUS
Isaac Dinis, Muskan Schinde, Nicolas Blind +11
The paper presents the DD4AO frequency‑domain, data‑driven adaptive optics controller, its implementation in the RISTRETTO instrument, and on‑sky validation with the PAPYRUS system…
Ground control to major time-lag: on-sky results of data-driven predictive wavefront control at Keck Observatory
Jules Fowler, Rebeca Jensen-Clem, Sylvain Cetre +12
Directly imaging and characterizing exoplanets requires extreme adaptive optics (XAO), which achieves exquisite wavefront correction over a small (<5") field of view. Temporal erro…
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…
On-sky demonstration of second-stage wavefront control with a photonic lantern
Aditya R. Sengupta, Jordan Diaz, Matthew DeMartino +14
Ground-based direct imaging of exoplanets at high contrast requires precise correction of atmospheric turbulence using adaptive optics (AO). The planet-to-star contrast ratio at sm…
The Santa Cruz Extreme AO Lab (SEAL) 2.0: A reflective, multi-wavelength rebuild
Rebecca Jensen-Clem, Vincent Chambouleyron, Prince Javier +20
The Santa cruz Extreme Adaptive optics Lab (SEAL) is a visible/near-infrared wavelength testbed designed to support technology development for high contrast imaging on large, segme…
