Revisiting the Borde-Traub focal plane wavefront estimation technique for exoplanet direct imaging
Axel Potier, A J Eldorado Riggs, Garreth Ruane +8
Direct imaging of exoplanets relies on complex wavefront sensing and control architectures. In addition to fast adaptive optics systems, most of the future high-contrast imaging in…
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…
Upgrading SPHERE with the second stage AO system SAXO+: non-common path aberrations estimation and correction
Johan Mazoyer, Charles Goulas, Fabrice Vidal +16
SAXO+ is a planned enhancement of the existing SAXO, the VLT/ SPHERE adaptive optics system, deployed on ESO's Very Large Telescope. This upgrade is designed to significantly enhan…
Numerical simulations for the SAXO+ upgrade: Performance analysis of the adaptive optics system
Charles Goulas, Raphaël Galicher, Fabrice Vidal +16
SPHERE, operating at the VLT since 2014, is currently one of the high-contrast instruments with a higher performance. Its adaptive optics system, known as SAXO, will be upgraded to…
Increasing the raw contrast of VLT/SPHERE with dark hole techniques III. Broadband reference differential imaging of HR\,4796 using a four-quadrant phase mask
Raphael Galicher, Axel Potier, Johan Mazoyer +3
Imaging exoplanetary systems is essential to characterizing exoplanetary systems and to studying planet-disk interactions to understand planet formation. Such imaging in the visibl…
