RHAPSODIE: Reconstruction of High-contrAst Polarized SOurces and Deconvolution for cIrcumstellar Environments
TL;DR: In this paper, a new method to extract the polarimetric signal using an inverse approach method that benefits from the added knowledge of the detected signal formation process is proposed. But the method is not suitable for high-contrast imaging and cannot be used in the case of low SNR/small polarized flux.

Exploiting the scaling indetermination of bi-linear models in inverse problems
TL;DR: In this paper, an unsupervised strategy to tune the hyper-parameter of a bi-linear model has been proposed, which has two benefits: hyperparameter tuning is simplified (a single parameter needs to be chosen) and the computation of the maximum a posteriori estimate is more efficient.
Proceedings ArticleDOI
Interbands phase models for polychromatic image reconstruction in optical interferometry
TL;DR: This paper presents an extension of the spatio-spectral (“3D”) image reconstruction algorithm called PAINTER (Polychromatic opticAl INTErferometric Reconstruction software), which is able to solve large scale problems and relies on an iterative process, which alternates estimation of polychromatic images and of complex visibilities.

TL;DR: An adaptive optics system with a single deformable mirror is being implemented on the THEMIS 90cm solar telescope as mentioned in this paper, which is designed to operate in the visible and is required to be as robust as possible in order to deliver the best possible correction in any atmospheric conditions, even if wavefronts are sensed on some low contrast solar granulation.

Image Reconstruction with VITRUV
TL;DR: In this paper, the authors have made simulations of what we can expect from the VLTI both with AMBER and the 8-way beam combining instrument project called VITRUV.
