The James Webb Space Telescope Mission: Optical Telescope Element Design, Development, and Performance
Michael W. McElwain, Lee D. Feinberg, Marshall D. Perrin +126
The James Webb Space Telescope (JWST) is a large, infrared space telescope that has recently started its science program which will enable breakthroughs in astrophysics and planeta…
The Nancy Grace Roman Space Telescope Coronagraph Instrument (CGI) Technology Demonstration
N. Jeremy Kasdin, Vanessa P. Bailey, Bertrand Mennesson +18
The Coronagraph Instrument (CGI) on the Nancy Grace Roman Space Telescope will demonstrate the high-contrast technology necessary for visible-light exoplanet imaging and spectrosco…
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…
