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…
Characterization and on-sky testing of photonic, AWG-based astronomical spectrographs
Jeronimo Calderon-Gomez, Frantz Martinache, Nick Cvetojevic +14
The paper presents the characterization of arrayed‑waveguide grating (AWG) photonic chips and their on‑sky testing with a high‑resolution near‑infrared spectrograph prototype, demo…
Optical gains measurement with a gain scheduling camera: On-sky demonstration with PAPYRUS and perspectives
A. Striffling, C. -T. Héritier, R. J. -L Fétick +4
Reaching the high angular resolution and contrast level desired for exoplanetary science requires us to equip large telescopes with extreme adaptive optics (XAO) systems to compens…
