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

no code implementations15 Dec 2020 Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady, Marcel Carbillet, Kjetil Dohlen, Julia Fowler, Iva Laginja, Matthew Maclay, James Noss, Marshall Perrin, Pete Petrone, Emiel Por, Jean-François Sauvage, Rémi Soummer, Arthur Vigan, Scott Will

To calibrate these pointing errors and other critical low-order aberrations, we propose a wavefront sensing path based on Zernike phase-contrast methods to analyze the starlight that is filtered out by the coronagraph at the telescope focus.
