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…
Wavefront error tolerancing for direct imaging of exo-Earths with a large segmented telescope in space
Iva Laginja, Lucie Leboulleux, Laurent Pueyo +8
Direct imaging of exo-Earths and search for life is one of the most exciting and challenging objectives for future space observatories. Segmented apertures in space will be require…
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…
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…
Phase-Retrieval-Based Wavefront Metrology for High Contrast Coronagraphy
Gregory R. Brady, Christopher Moriarty, Peter Petrone +5
We discuss the use of parametric phase-diverse phase retrieval as an in-situ high-fidelity wavefront measurement method to characterize and optimize the transmitted wavefront of a…
