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…
Slow focus sensor for the Keck I laser guide star adaptive optics system using focal plane wavefront sensing
Rafael M. Salgueiro, Carlos M. Correia, Benoit Neichel +7
Laser guide stars (LGSs) have been deployed for the last 20-30 years in ground-based astronomical telescopes to overcome the limited sky coverage of classical adaptive optics (AO)…
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…
Estimating differential pistons for the Extremely Large Telescope using focal plane imaging and a residual network
P. Janin-Potiron, M. Gray, B. Neichel +6
As the Extremely Large Telescope (ELT) approaches operational status, optimising its imaging performance is critical. A differential piston, arising from either the adaptive optics…
