Experimental demonstration of spectral linear dark field control at NASA's high contrast imaging testbeds
Phillip K. Poon, Axel Potier, Garreth Ruane +6
Due to the low flux of exoEarths, long exposure times are required to spectrally characterize them. During these long exposures, the contrast in the dark hole will degrade as the t…
FALCO simulations of high-contrast polarimetry with the Nancy Grace Roman Space Telescope Coronagraph Instrument
David S. Doelman, Hanae Belaouchi, A. J. Riggs +6
The Coronagraph Instrument of the Nancy Grace Roman Space Telescope (Roman Coronagraph) will be capable of both total intensity and polarization measurements of circumstellar disks…
Benefits of adding radial phase dimples on scalar coronagraph phase masks
Niyati Desai, Dimitri Mawet, Eugene Serabyn +4
Current scalar coronagraph focal plane mask designs are performance-limited by chromaticity. We investigate the effects of adding central Roddier and dual zone phase dimples to sca…
Comparative laboratory study of electric field conjugation algorithms
Niyati Desai, Axel Potier, Susan F. Redmond +5
Future space telescope coronagraph instruments hinge on the integration of high-performance masks and precise wavefront sensing and control techniques to create dark holes essentia…
Dual Purpose Lyot Coronagraph Masks for Simultaneous High-Contrast Imaging and High-Resolution Wavefront Sensing
Garreth Ruane, J. Kent Wallace, A J Eldorado Riggs +8
Directly imaging Earth-sized exoplanets with a visible-light coronagraph instrument on a space telescope will require a system that can achieve raw contrast and main…
Random Vibration Testing of Microelectromechanical Deformable Mirrors for Space-based High-Contrast Imaging
Axel Potier, Camilo Mejia Prada, Garreth Ruane +11
Space-based stellar coronagraph instruments aim to directly image exoplanets that are a fraction of an arcsecond separation and ten billion times fainter than their host star. To a…
Laboratory demonstration of the wrapped staircase scalar vortex coronagraph
Niyati Desai, Garreth J. Ruane, Jorge D. Llop-Sayson +5
Of the over 5000 exoplanets that have been detected, only about a dozen have ever been directly imaged. Earth-like exoplanets are on the order of 10 billion times fainter than thei…
