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…
DM/WFS mis-registration tracking: Implementation and on-sky validation of SPRINT at LBT
Ben Buky, Cédric Taïssir Héritier, Fabio Rossi +7
The paper describes the implementation of the SPRINT method on the Large Binocular Telescope to track and correct mis‑registrations between the deformable mirror and wavefront sens…
Towards an Extended VLTI: Turbulence Characterization for Kilometer-Scale Optical Links at Paranal
B. Neichel, T. Pichon, G. Bourdarot +10
The paper investigates the feasibility of extending the VLTI to kilometer-scale baselines by using free-space optical links with adaptive‑optics pre‑compensation, and proposes a de…
Estimation of the laser guide star uplink tip-tilt using aperture size diversity
Pierre Jouve, Thierry Fusco, Carlos M. Correia +3
The paper proposes a method to estimate the uplink tip‑tilt of a laser guide star using only telemetry from the launch telescope, by exploiting aperture size diversity and an LMMSE…
Super-resolution wavefront reconstruction in adaptive-optics with pyramid sensors
Carlos M. Correia, Charlotte Z. Bond, João Aveiro +3
Super-resolution (SR) refers to a combination of optical design and signal processing techniques jointly employed to obtain reconstructed wave-fronts at a higher-resolution from mu…
Super-resolution-enabled atmospheric tomography for astronomical multi-wavefront-sensor adaptive-optics systems
Carlos M. Correia, Pierre Jouve, Jesse Cranney +1
Recent work by Oberti et al, (Astron. Astrophys., 667, 48, 2022) argued and made a compelling case that classical astronomical adaptive optics (AO) tomography performance can be fu…
