Reinforcement learning for post-coronagraphic wavefront control
Manuela Castañeda-Medina, Yann Gutierrez, Johan Mazoyer +3
Direct imaging of exoplanets is limited by the extreme contrast between the star and the planets, which is mitigated using a coronagraph. However, optical aberrations cause starlig…

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…
