Diffusion models for polarimetric reconstruction of circumstellar environments
Quentin Villegas, Laurence Denneulin, Simon Prunet +5
In this paper, we propose an approach combining diffusion models and inverse problems for the reconstruction of circumstellar disk images. Our method builds upon the Rhapsodie fram…
REXPACO: an algorithm for high contrast reconstruction of the circumstellar environment by angular differential imaging
Olivier Flasseur, Samuel Thé, Loïc Denis +2
Aims. The purpose of this paper is to describe a new post-processing algorithm dedicated to the reconstruction of the spatial distribution of light received from off-axis sources,…
RHAPSODIE: Reconstruction of High-contrAst Polarized SOurces and Deconvolution for cIrcumstellar Environments
Laurence Denneulin, Maud Langlois, Éric Thiébaut +1
Polarimetric imaging is one of the most effective techniques for high-contrast imaging and characterization of circumstellar environments. These environments can be characterized t…
The wavefront sensing making-of for THEMIS solar telescope
Michel Tallon, Éric Thiébaut, Maud Langlois +5
An adaptive optics system with a single deformable mirror is being implemented on the THEMIS 90cm solar telescope. This system is designed to operate in the visible and is required…
PeX 1. Multi-spectral expansion of residual speckles for planet detection
Nicholas Devaney, Éric Thiébaut
The detection of exoplanets in coronographic images is severely limited by residual starlight speckles. Dedicated post-processing can drastically reduce this "stellar leakage" and…
