Closing the loop on-sky with a vector-Zernike wavefront sensor using a convolutional neural network as phase reconstructor
Francisco Oyarzún, Mathieu Motte, Cedric-Taissir Heritier +11
Context: The new giant segmented mirror telescopes will use adaptive optics to reach the fundamental limits in resolving power. To accomplish this, new wavefront sensors (WFS) have…
Cassiopee: Defining the next-generation deformable mirror and high-speed SWIR camera for adaptive optics applications
B. Neichel, T. Fusco, F. Oyarzun +14
Future adaptive optics (AO) systems for astronomy, optical communications, space situational awareness, and laser-based defense require a new generation of components operating at…
Towards an Extended VLTI: Turbulence Characterization for Kilometer-Scale Optical Links at Paranal
B. Neichel, T. Pichon, G. Bourdarot +10
The paper investigates the feasibility of extending the VLTI to kilometer-scale baselines by using free-space optical links with adaptive‑optics pre‑compensation, and proposes a de…
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…
Experimentally-determined performance limits for joint imaging and wavefront sensing with a photonic lantern
Aditya R. Sengupta, Vincent Chambouleyron, Rebecca Jensen-Clem +16
The photonic lantern (PL) is a focal-plane wavefront sensor (WFS) that can be used for second-stage control of extreme adaptive optics (AO) systems. While the number of sensed mode…
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…
