Context. The direct imaging of potentially habitable exoplanets is one prime science case for
the next generation of high contrast imaging instruments on ground-based, extremely large …

As we look to the next generation of adaptive optics systems, now is the time to develop and
explore the technologies that will allow us to image rocky Earth-like planets; wavefront …

We present a novel formulation of closed-loop adaptive optics (AO) control as a multi-agent
reinforcement learning (MARL) problem in which the controller is able to learn a non-linear …

The pyramid wave front sensor (PyWFS) has become increasingly popular to use in
adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is …

We propose a novel control approach that combines offline supervised learning to address
the challenges posed by non-linear phase reconstruction using unmodulated pyramid …

Optical aberrations prevent telescopes from reaching their theoretical diffraction limit. Once
estimated, these aberrations can be compensated for using deformable mirrors in a closed …

Almost all current and future high-contrast imaging instruments will use a Pyramid wavefront
sensor (PWFS) as a primary or secondary wavefront sensor. The main issue with the PWFS …

We present a model-free reinforcement learning (RL) predictive model with a supervised
learning non-linear reconstructor for adaptive optics (AO) control with a pyramid wavefront …

Direct imaging of Earth-like exoplanets is one of the significant scientific drivers of the next
generation of ground-based telescopes. Typically, Earth-like exoplanets are located at tiny …
