Co-design approach to aperture masking for imaging through atmospheric turbulence
Olivier Herscovici-Schiller, Laurent M. Mugnier, Alice Fontbonne +5
Aperture masking interferometry is a technique originally designed to alleviate the influence of atmospheric turbulence on images recorded on ground-based telescopes. In this commu…

A Deep Reinforcement Learning Approach to Wavefront Control for Exoplanet Imaging
Yann Gutierrez, Johan Mazoyer, Olivier Herscovici-Schiller +3
Exoplanet imaging uses coronagraphs to block out the bright light from a star, allowing astronomers to observe the much fainter light from planets orbiting the star. However, these…

Image-based wavefront correction using model-free Reinforcement Learning
Yann Gutierrez, Johan Mazoyer, Laurent M. Mugnier +2
Optical aberrations prevent telescopes from reaching their theoretical diffraction limit. Once estimated, these aberrations can be compensated for using deformable mirrors in a clo…
