HARMONI at ELT: A Zernike wavefront sensor for the high-contrast module -- Testbed results with realistic observation conditions
Adrien Hours, Alexis Carlotti, David Mouillet +10
ELT-HARMONI is the first light visible and near-IR integral field spectrograph (IFS) for the ELT. It covers a large spectral range from 450nm to 2450nm with resolving powers from 3…
Coronagraphy for DiRect Imaging of Exoplanets (CIDRE) testbed 1: concept, optical set up, and experimental results of adaptive amplitude apodization
Lucie Leboulleux, Alexis Carlotti, Stéphane Curaba +5
Oncoming exoplanet spectro-imagers like the Planetary Camera and Spectrograph (PCS) for the Extremely Large Telescope (ELT) will aim for a new class of exoplanets, including Earth-…
Redundant Apodized Pupils (RAP) for high-contrast imagers robust to segmentation-due aberrations and island effects
Lucie Leboulleux, Alexis Carlotti, Mamadou N'Diaye +6
The imaging and characterization of a larger range of exoplanets, down to young Jupiters and exo-Earths will require accessing very high contrasts at small angular separations with…
Redundant apodization for direct imaging of exoplanets 2: Application to island effects
Lucie Leboulleux, Alexis Carlotti, Mamadou N'Diaye +6
Telescope pupil fragmentation from spiders generates specific aberrations observed at various telescopes and expected on the large telescopes under construction. This so-called isl…
Redundant apodization for direct imaging of exoplanets I: Robustness to primary mirror segmentation-induced errors outside the segment diffraction limit
Lucie Leboulleux, Alexis Carlotti, Mamadou N'Diaye
Direct imaging and spectroscopy of Earth-like planets and young Jupiters require contrasts up to 10^6-10^10 at angular separations of a few dozen milliarcseconds. To achieve this g…
