New method to achieve the proper polarization state for a vector vortex coronagraph
Jorge Llop-Sayson, Cole Kappel, Nemanja Jovanovic +1
The vector vortex coronagraph (VVC) performance in the laboratory and in ground-based observatories has earned it a spot on the NASA mission concepts HabEx and LUVOIR. The VVC indu…
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…
High-contrast Demonstration of an Apodized Vortex Coronagraph
Jorge Llop-Sayson, Garreth Ruane, Dimitri Mawet +7
High contrast imaging is the primary path to the direct detection and characterization of Earth-like planets around solar-type stars; a cleverly designed internal coronagraph suppr…
Enabling the next generation of scientific discoveries by embracing photonic technologies
Nemanja Jovanovic, Charles Beichman, Cullen Blake +46
The fields of Astronomy and Astrophysics are technology limited, where the advent and application of new technologies to astronomy usher in a flood of discoveries altering our unde…
Simulations of a High-Contrast Single-Mode Fiber Coronagraphic Multi-Object Spectrograph for Future Space Telescopes
Carl T. Coker, Stuart B. Shaklan, A J E. Riggs +1
Directly imaging and characterizing Earth-like exoplanets is a tremendously difficult instrumental challenge. Present coronagraphic systems have yet to achieve the required $10^{-1…
High-contrast spectroscopy testbed for Segmented Telescopes: instrument overview and development progress
N. Jovanovic, G. Ruane, D. Echeverri +11
The High Contrast spectroscopy testbed for Segmented Telescopes (HCST) is being developed at Caltech. It aims at addressing the technology gap for future exoplanet imagers and prov…
