Real-time control and data standardization on various telescopes and benches
Nour Skaf, Rebecca Jensen-Clem, Aaron Hunter +19
Real-time control (RTC) is pivotal for any Adaptive Optics (AO) system, including high-contrast imaging of exoplanets and circumstellar environments. It is the brain of the AO syst…
High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control
Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27
We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…
High-contrast imager for complex aperture telescopes (HiCAT): 11. System-level demonstration of the Apodized Pupil Lyot Coronagraph with a segmented aperture in air
Rémi Soummer, Raphaël Pourcelot, Emiel H. Por +16
We present the final results of the Apodized Pupil Lyot Coronagraph (APLC) on the High-contrast imager for Complex Aperture Telescopes (HiCAT) testbed, under NASA's Strategic Astro…
Simulated performance of energy-resolving detectors towards exoplanet imaging with the Habitable Worlds Observatory
Sarah Steiger, Laurent Pueyo, Emiel H. Por +5
One of the primary science goals of the Habitable Worlds Observatory (HWO) as defined by the Astro2020 decadal survey is the imaging of the first Earth-like planet around a Sun-lik…
Mid-order wavefront control for exoplanet imaging: preliminary characterization of the segmented deformable mirror and Zernike wavefront sensor on HiCAT
B. Buralli, M. N'Diaye, R. Pourcelot +13
We study a mid-order wavefront sensor (MOWFS) to address fine cophasing errors in exoplanet imaging with future large segmented aperture space telescopes. Observing Earth analogs a…
METIS high-contrast imaging: from final design to manufacturing and testing
Olivier Absil, Matthew Kenworthy, Christian Delacroix +21
The Mid-infrared ELT Imager and Spectrograph (METIS) is one of the first-generation scientific instruments for the ELT, built under the supervision of ESO by a consortium of resear…
