PROVIDENCE: a ground station for space observation
P. -L. Mayeur, J. -F. Sauvage, T. Fusco +25
PROVIDENCE is an ONERA-led project to install a new-generation optical ground station at the Haute-Provence Observatory (OHP) in South of France. Built around a 2.5-meter aperture,…
High-contrast imager for Complex Aperture Telescopes (HiCAT): 3. first lab results with wavefront control
Mamadou N'Diaye, Johan Mazoyer, Elodie Choquet +9
HiCAT is a high-contrast imaging testbed designed to provide complete solutions in wavefront sensing, control and starlight suppression with complex aperture telescopes. The pupil…
High-contrast imager for complex aperture telescopes (HiCAT): 5. first results with segmented-aperture coronagraph and wavefront control
Remi Soummer, Gregory R. Brady, Keira Brooks +19
Segmented telescopes are a possibility to enable large-aperture space telescopes for the direct imaging and spectroscopy of habitable worlds. However, the complexity of their apert…
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…
Capabilities of ACAD-OSM, an active method for the correction of aperture discontinuities
Johan Mazoyer, Laurent Pueyo, Mamadou N'Diaye +4
The increasing complexity of the aperture geometry of the future space- and ground based-telescopes will limit the performance of the next generation of coronagraphic instruments f…
High-contrast imager for Complex Aperture Telescopes (HiCAT): 2. Design overview and first light results
Mamadou N'Diaye, Elodie Choquet, Sylvain Egron +13
We present a new high-contrast imaging testbed designed to provide complete solutions in wavefront sensing, control and starlight suppression with complex aperture telescopes. The…
James Webb Space Telescope Optical Simulation Testbed I: Overview and First Results
Marshall D. Perrin, Rémi Soummer, Élodie Choquet +13
The James Webb Space Telescope (JWST) Optical Simulation Testbed (JOST) is a tabletop workbench to study aspects of wavefront sensing and control for a segmented space telescope, i…
