James Webb Space Telescope Optical Simulation Testbed V: Wide-field phase retrieval assessment
Iva Laginja, Greg Brady, Remi Soummer +14
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a hardware simulator for wavefront sensing and control designed to produce JWST-like images. A model of t…
SCExAO, an instrument with a dual purpose: perform cutting-edge science and develop new technologies
Julien Lozi, Olivier Guyon, Nemanja Jovanovic +31
The Subaru Coronagraphic Extreme Adaptive Optics (SCExAO) instrument is an extremely modular high-contrast instrument installed on the Subaru telescope in Hawaii. SCExAO has a dual…
Low Wind Effect on VLT/SPHERE : impact, mitigation strategy, and results
Julien Milli, Markus Kasper, Pierre Bourget +14
The low wind effect is a phenomenon disturbing the phase of the wavefront in the pupil of a large telescope obstructed by spiders, in the absence of wind. It can be explained by th…
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…
Review of high-contrast imaging systems for current and future ground- and space-based telescopes I. Coronagraph design methods and optical performance metrics
G. Ruane, A. Riggs, J. Mazoyer +29

SPHERE on-sky performance compared with budget predictions
Kjetil Dohlen, Arthur Vigan, David Mouillet +21
The SPHERE (spectro-photometric exoplanet research) extreme-AO planet hunter saw first light at the VLT observatory on Mount Paranal in May 2014 after ten years of development. Gre…
Pair-based Analytical model for Segmented Telescopes Imaging from Space (PASTIS) for sensitivity analysis
Lucie Leboulleux, Jean-François Sauvage, Laurent Pueyo +6
The imaging and spectroscopy of habitable worlds will require large-aperture space-based telescopes, to increase the collecting area and the angular resolution. These large telesco…
On-sky compensation of non-common path aberrations with the ZELDA wavefront sensor in VLT/SPHERE
A. Vigan, M. N'Diaye, K. Dohlen +7
Circumstellar environments are now routinely observed by dedicated high-contrast imagers on large, ground-based observatories. These facilities combine extreme adaptive optics and…
