PROVIDENCE: scientific and programmatic roadmap of a 2.5-m adaptive-optics telescope dedicated to space domain awareness, astronomy, and free-space optics

Space Domain Awareness (SDA) is crucial for defense and civilian use. Ground based high resolution imaging with large telescopes and adaptive optics can deliver detailed image sequences of resident space objects (RSO), complemented by additional signatures for characterization. ONERA, together with CNRS/OSU Pythéas, is...

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...
