Experimental validation of active control of low-order aberrations with a Zernike sensor through a Lyot coronagraph
Raphaël Pourcelot, Mamadou N'Diaye, Emiel H. Por +11
Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 10^10 contra…
Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging
Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13
Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
Predicting contrast sensitivity to segmented aperture misalignment modes for the HiCAT testbed
Iva Laginja, Remi Soummer, Laurent M. Mugnier +10
This paper presents the setup for empirical validations of the Pair-based Analytical model for Segmented Telescope Imaging from Space (PASTIS) tolerancing model for segmented coron…
Laboratory Demonstration of Spatial Linear Dark Field Control For Imaging Extrasolar Planets in Reflected Light
Thayne Currie, Eugene Pluzhnik, Olivier Guyon +15
Imaging planets in reflected light, a key focus of future NASA missions and ELTs, requires advanced wavefront control to maintain a deep, temporally correlated null of stellar halo…
