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-…
Vortex-phase filtering technique for extracting spatial information from unresolved sources
Garreth J. Ruane, Prachyathit Kanburapa, Jiaxuan Han +1
A white light vortex coronagraph was used to experimentally achieve sub-resolution detection. The angular location of the centroid, , and the angular extent of circular pinhole…
Nodal Areas and Structured Darkness
Garreth J. Ruane, Sergei Slussarenko, Lorenzo Marrucci +1
Generalized beams of light that are made to turn inside out, creating black nodal areas of total destructive interference are described. As an example we experimentally created an…
