APLC-Optimization: an apodized pupil Lyot coronagraph design survey toolkit
Bryony F. Nickson, Emiel H. Por, Meiji M. Nguyen +9
We present a publicly available software package developed for exploring apodized pupil Lyot coronagraph (APLC) solutions for various telescope architectures. In particular, the pa…
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…
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 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…
Calibration of quasi-static aberrations in exoplanet direct-imaging instruments with a Zernike phase-mask sensor. IV. Temporal stability of non-common path aberrations in VLT/SPHERE
A. Vigan, K. Dohlen, M. N'Diaye +12
Coronagraphic imaging of exoplanets using ground-based instruments on large telescopes is intrinsically limited by speckles induced by uncorrected aberrations. These aberrations or…
Design of the vacuum high contrast imaging testbed for CDEEP, the Coronagraphic Debris and Exoplanet Exploring Pioneer
Erin R. Maier, Ewan S. Douglas, Daewook Kim +26
The Coronagraphic Debris Exoplanet Exploring Payload (CDEEP) is a Small-Sat mission concept for high contrast imaging of circumstellar disks. CDEEP is designed to observe disks in…
