Diffusion Models for Polarimetric Reconstruction of Circumstellar Environments in Correlated Speckle Noise
Quentin Villegas, Laurence Denneulin, Simon Prunet +3
High-contrast polarimetric imaging of circumstellar disks is severely limited by stellar leakage and speckle noise. Building upon the RHAPSODIE framework for polarimetric inverse p…
I2C@2024: an interferometric imaging contest in 2024
Florentin Millour, Mathis Houll{é}, Jeremy Perdigon +6
Images in optical long-baseline interferometry have seen a boost in the recent years thanks to new techniques and recipes invented by the community. These images are more and more…
Calibrations for high precision differential astrometry onboard Theia and HWO
Manon Lizzana, Fabien Malbet, Hugo Rousset +3
Future space astrometry missions such as Theia and an astrometric mode of the Habitable Worlds Observatory (HWO) require detector calibration and instrumental characterization at a…
Optimization of adaptive optics correction during observations: Algorithms and system parameters identification in closed-loop
Clémentine Béchet, Michel Tallon, Éric Thiébaut
The adaptive optics (AO) on the European Extremely Large Telescope, as well as earlier pathfinders like the Adaptive Optics Facility, at the Very Large Telescope in 2014, will no l…
Pixel-Level Calibration for Space-Based High Precision Astrometry Using Young's Fringes
Hugo Rousset, Eric Thiébaut, Chloé Rey +8
The detection of Earth-like exoplanets via astrometry necessitates centroiding precision at the 0.3 microarcsec level, thereby imposing stringent constraints on the focal plane geo…
Closing the loop as an inverse problem: the real-time control of THEMIS adaptive optics
Éric Thiébaut, Michel Tallon, Isabelle Tallon-Bosc +4
We have taken advantage of the implementation of an adaptive optics system on the Themis solar telescope to implement innovative strategies based on an inverse problem formulation…
