Development of an ELT XAO testbed using a Mach-Zehnder wavefront sensor: calibration of the deformable mirror
Christian Delacroix, Maud Langlois, Magali Loupias +4
(abridged) Extreme adaptive optics (XAO) encounters severe difficulties to cope with the high speed (>1kHz), high accuracy and high order requirements for future extremely large te…
Optimized focal and pupil plane masks for vortex coronagraphs on telescopes with obstructed apertures
Garreth J. Ruane, Olivier Absil, Elsa Huby +5
We present methods for optimizing pupil and focal plane optical elements that improve the performance of vortex coronagraphs on telescopes with obstructed or segmented apertures. P…
Lyot-plane phase masks for improved high-contrast imaging with a vortex coronagraph
Garreth J. Ruane, Elsa Huby, Olivier Absil +4
The vortex coronagraph is an optical instrument that precisely removes on-axis starlight allowing for high contrast imaging at small angular separation from the star, thereby provi…
