Solar Sail Propulsion by 2050: An Enabling Capability for Heliophysics Missions
Les Johnson, Nathan Barnes, Matteo Ceriotti +11
Solar sails enable missions to observe the solar environment from unique vantage points, such as sustained observations away from the Sun-Earth line; sub-L1 station keeping; high i…
Randomized Aperture Imaging
Xiaopeng Peng, Garreth J. Ruane, Grover A. Swartzlander
Speckled images of a binary broad band light source (600-670 nm), generated by randomized reflections or transmissions, were used to reconstruct a binary image by use of multi-fram…
Optimized focal and pupil plane masks for vortex coronagraphs on telescopes with obstructed apertures
Garreth J. Ruane, Olivier Absil, Elsa Huby +5
We present methods for optimizing pupil and focal plane optical elements that improve the performance of vortex coronagraphs on telescopes with obstructed or segmented apertures. P…
Lyot-plane phase masks for improved high-contrast imaging with a vortex coronagraph
Garreth J. Ruane, Elsa Huby, Olivier Absil +4
The vortex coronagraph is an optical instrument that precisely removes on-axis starlight allowing for high contrast imaging at small angular separation from the star, thereby provi…
