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…
