Predictive wavefront control on Keck II adaptive optics bench: on-sky coronagraphic results

Maaike A. M. van Kooten, Rebecca Jensen-Clem Sylvain Cetre, Sam Ragland +3

The behavior of an adaptive optics (AO) system for ground-based high contrast imaging (HCI) dictates the achievable contrast of the instrument. In conditions where the coherence ti…

Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging

Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13

Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
