Impact of microlens shape on the performance of Laser Guide Star wavefront sensors for ELT-class telescopes
Paul Rouquette, Benoit Neichel, Cédric Taisir Heritierc +4
Laser Guide Star (LGS) adaptive optics systems on extremely large telescopes (ELTs) rely on Shack-Hartmann wavefront sensors (SHWFS) equipped with large-format microlens arrays. Ma…

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…
