Mid-order wavefront control for exoplanet imaging: preliminary characterization of the segmented deformable mirror and Zernike wavefront sensor on HiCAT

Buralli, Benjamin N'Diaye, Mamadou Pourcelot, Raphaël

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 around Sun-like stars requires contrasts down to 10^-10 in visible light. One promising solution consists of producing a high-contrast dark zone in the image of an...
