On-sky demonstration of a vector Zernike wavefront sensor in a cascaded adaptive optics system
Future high-contrast instruments aim to directly image and characterise Earth-like exoplanets. Achieving the required contrast requires exquisite image quality, and in particular a high-performance correction of the optical aberrations. Hence, future instruments will use adaptive optics (AO) systems operating at increa...
