On-sky demonstration of a vector Zernike wavefront sensor in a cascaded adaptive optics system
M. Motte, V. Chambouleyron, R. Fétick +13
To directly image and characterise Earth-like exoplanets, future high-contrast instruments will require adaptive-optics systems operating at increasingly high loop frequencies to r…

Closing the loop on-sky with a vector-Zernike wavefront sensor using a convolutional neural network as phase reconstructor
Francisco Oyarzún, Mathieu Motte, Cedric-Taissir Heritier +11
Context: The new giant segmented mirror telescopes will use adaptive optics to reach the fundamental limits in resolving power. To accomplish this, new wavefront sensors (WFS) have…
