Rigorous vector wave propagation for arbitrary flat media
Steven P. Bos, Sebastiaan Y. Haffert, Christoph U. Keller
Precise modelling of the (off-axis) point spread function (PSF) to identify geometrical and polarization aberrations is important for many optical systems. In order to characterise…
SPHERE / ZIMPOL high resolution polarimetric imager. I. System overview, PSF parameters, coronagraphy, and polarimetry
H. M. Schmid, A. Bazzon, R. Roelfsema +59
We describe the Zurich Imaging Polarimeter (ZIMPOL), the visual focal plane subsystem of the SPHERE "VLT planet finder", which pushes the limits of current AO systems to shorter wa…
Multiplexed Holographic Aperture Masking with liquid-crystal geometric phase masks
David S. Doelman, Peter Tuthill, Barnaby Norris +5
Sparse Aperture Masking (SAM) allows for high-contrast imaging at small inner working angles, however the performance is limited by the small throughput and the number of baselines…
Chromatic transit light curves of disintegrating rocky planets
A. R. Ridden-Harper, C. U. Keller, M. Min +2
Context. Kepler observations have revealed a class of short period exoplanets, of which Kepler-1520 b is the prototype, which have comet-like dust tails thought to be the result of…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes III. Technology opportunities and pathways
Frans Snik, Olivier Absil, Pierre Baudoz +30
The Optimal Optical CoronagraphWorkshop at the Lorentz Center in September 2017 in Leiden, the Netherlands gathered a diverse group of 25 researchers working on exoplanet instrumen…
Review of high-contrast imaging systems for current and future ground-based and space-based telescopes II. Common path wavefront sensing/control and Coherent Differential Imaging
Nemanja Jovanovic, Olivier Absil, Pierre Baudoz +28
The Optimal Optical Coronagraph (OOC) Workshop held at the Lorentz Center in September 2017 in Leiden, the Netherlands, gathered a diverse group of 25 researchers working on exopla…
