Development of a subwavelength grating vortex coronagraph of topological charge 4 (SGVC4)
Christian Delacroix, Olivier Absil, Brunella Carlomagno +6
One possible solution to achieve high contrast direct imaging at a small inner working angle (IWA) is to use a vector vortex coronagraph (VVC), which provides a continuous helical…
The VORTEX project: first results and perspectives
Olivier Absil, Dimitri Mawet, Christian Delacroix +15
(abridged) Vortex coronagraphs are among the most promising solutions to perform high contrast imaging at small angular separations. They feature a very small inner working angle,…
Fundamental limitations of high contrast imaging set by small sample statistics
Dimitri Mawet, Julien Milli, Zahed Wahhaj +9
In this paper, we review the impact of small sample statistics on detection thresholds and corresponding confidence levels (CLs) in high contrast imaging at small angles. When look…
