High-Contrast Testbeds for Future Space-Based Direct Imaging Exoplanet Missions
Johan Mazoyer, Pierre Baudoz, Ruslan Belikov +25
Instrumentation techniques in the field of direct imaging of exoplanets have greatly advanced over the last two decades. Two of the four NASA-commissioned large concept studies inv…
Three years of harvest with the vector vortex coronagraph in the thermal infrared
Olivier Absil, Dimitri Mawet, Mikael Karlsson +25
For several years, we have been developing vortex phase masks based on sub-wavelength gratings, known as Annular Groove Phase Masks. Etched onto diamond substrates, these AGPMs are…
Zernike amplitude pupil apodization for vortex coronagraphy with obscured apertures
Garreth J. Ruane, Mark R. Dennis, Grover A. Swartzlander
A set of pupil apodization functions for use with a vortex coronagraph on telescopes with obscured apertures is presented. We show analytically that pupil amplitudes given by real-…
