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…
Cascade adaptive optics with a second stage based on a Zernike wavefront sensor for exoplanet observations
M. N'Diaye, A. Vigan, B. Engler +7
Over the past decade, the high-contrast observation of disks and gas giant planets around nearby stars has been made possible on ground-based instruments using extreme adaptive opt…
The GPU-based High-order adaptive OpticS Testbench
Byron Engler, Markus Kasper, Serban Leveratto +12
The GPU-based High-order adaptive OpticS Testbench (GHOST) at the European Southern Observatory (ESO) is a new 2-stage extreme adaptive optics (XAO) testbench at ESO. The GHOST is…
Laboratory Experiments of Model-based Reinforcement Learning for Adaptive Optics Control
Jalo Nousiainen, Byron Engler, Markus Kasper +5
Direct imaging of Earth-like exoplanets is one of the most prominent scientific drivers of the next generation of ground-based telescopes. Typically, Earth-like exoplanets are loca…
Exoplanet imaging with ELTs: exploring a second-stage AO with a Zernike wavefront sensor on the ESO/GHOST testbed
Mamadou N'Diaye, Arthur Vigan, Byron Engler +6
We propose to explore a cascade extreme Adaptive optics (ExAO) approach with a second stage based on a Zernike wavefront sensor (ZWFS) for exoplanet imaging and spectroscopy. Most…
