Analytical modelling of adaptive optics systems: Role of the influence function
Anthony Berdeu, Michel Tallon, Éric Thiébaut +1
Context. Adaptive optics (AO) is now a tool commonly deployed in astronomy. The real time correction of the atmospheric turbulence that AO enables allows telescopes to perform clos…
Inverse problem approach in Extreme Adaptive Optics: analytical model of the fitting error and lowering of the aliasing
Anthony Berdeu, Michel Tallon, Éric Thiébaut +5
We present the results obtained with an end-to-end simulator of an Extreme Adaptive Optics (XAO) system control loop. It is used to predict its on-sky performances and to optimise…
Adaptive Optics system of the Evanescent Wave Coronagraph (EvWaCo): optimised phase plate and DM characterisation
Anthony Berdeu, Sitthichat Sukpholtham, Puttiwat Kongkaew +6
The Evanescent Wave Coronagraph (EvWaCo) is an achromatic coronagraph mask with adjustable size over the spectral domain [600nm, 900nm] that will be installed at the Thai National…
Deep Contrast and Companion Detection Using the EvWaCo Testbed Equipped with an Achromatic Focal Plane Mask and an Adjustable Inner Working Angle
M. A. Alagao, A. Kawinkij, C. Buisset +21
The evanescent wave coronagraph uses the principle of frustrated total internal reflection (FTIR) to suppress the light coming from the star and study its close environment. Its fo…
