Experimental validation of coronagraphic focal-plane wavefront sensing for future segmented space telescopes
Lucie Leboulleux, Jean-François Sauvage, Rémi Soummer +6
Direct imaging of Earth-like planets from space requires dedicated observatories, combining large segmented apertures with instruments and techniques such as coronagraphs, wavefron…
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…
High-contrast Imager for Complex Aperture Telescopes (HiCAT): 6. Software Control Infrastructure and Calibration
Christopher Moriarty, Keira Brooks, Remi Soummer +5
High contrast imaging using coronagraphy is one of the main avenues to enable the search for life on extrasolar Earth analogs. The HiCAT testbed aims to demonstrate coronagraphy an…
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…
Phase-Occultation Nulling Coronagraphy
Richard G. Lyon, Brian A. Hicks, Mark Clampin +1
The search for life via characterization of earth-like planets in the habitable zone is one of the key scientific objectives in Astronomy. We describe a new phase-occulting (PO) in…
