The infrared unmodulated pyramid wavefront sensor: simulations, lab and on sky
Muskan Shinde, Nicolas Blind, Isaac Dinis +13
Direct imaging of Earth-like exoplanets requires strong suppression of stellar light at small angular separations, achievable with extreme adaptive optics (XAO). The pyramid wavefr…
RAMA: A new agile AO bench for the telescope FEELINGS
Matteo Pasinetti, Rodrigo Andres Munoz Gomez, Benjamin Andres Gonzalez Barraza +16
The ground-based observation of extended objects such as satellites suffer from severe atmospheric propagation constraints. Specifically, high tracking velocities and low-elevation…
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…
Performance comparison of the Shack-Hartmann and pyramid wavefront sensors with a laser guide star for 40 m telescopes
Francisco Oyarzun, Cedric-Taissir Heritier, Vincent Chambouleyron +3
Context. The new giant segmented mirror telescopes will use laser guide stars (LGS) for their adaptive optics (AO) systems. Two options to use as wavefront sensors (WFS) are the Sh…
Expected performance of the Pyramid wavefront sensor with a laser guide star for 40 m class telescopes
Francisco Oyarzún, Vincent Chambouleyron, Benoit Neichel +2
The use of artificial Laser Guide Stars (LGS) is planned for the new generation of giant segmented mirror telescopes, to extend the sky coverage of their adaptive optics systems. T…
