Wavefront sensing and control in space-based coronagraph instruments using Zernike's phase-contrast method
Garreth Ruane, J. Kent Wallace, John Steeves +14
Future space telescopes with coronagraph instruments will use a wavefront sensor (WFS) to measure and correct for phase errors and stabilize the stellar intensity in high-contrast…
Microelectromechanical deformable mirror development for high-contrast imaging, part 2: the impact of quantization errors on coronagraph image contrast
Garreth Ruane, Daniel Echeverri, Eduardo Bendek +8
Stellar coronagraphs rely on deformable mirrors (DMs) to correct wavefront errors and create high contrast images. Imperfect control of the DM limits the achievable contrast and, t…
Paving the Way to Future Missions: the Roman Space Telescope Coronagraph Technology Demonstration
B. Mennesson, R. Juanola-Parramon, B. Nemati +33
This document summarizes how far the Nancy Grace Roman Space Telescope Coronagraph Instrument (Roman CGI) will go toward demonstrating high-contrast imaging and spectroscopic requi…
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…
