Temporal regularization of petal modes in SCAO systems: The Soft-Limiter approach
Guido Agapito, Jueqi Lin, Carmelo Arcidiacono +3
Extremely large telescopes (ELTs) rely on segmented mirrors and thick support structures that fragment the pupil. In single-conjugate AO (SCAO), this produces differential pistons,…
Characterization of the MUSE NFM PSF as a function of atmospheric conditions: TipTop calibration
Enrico Congiu, Fuyan Bian, Carlo F. Manara +8
The Multi Unit Spectroscopic Explorer (MUSE) achieves exceptional spatial resolution in narrow-field mode (NFM) thanks to the GALACSI adaptive optics (AO) system. However, limitati…
DM/WFS mis-registration tracking: Implementation and on-sky validation of SPRINT at LBT
Ben Buky, Cédric Taïssir Héritier, Fabio Rossi +7
The advent of telescopes with an integrated deformable mirror (DM) presents new challenges for adaptive optics (AO) systems. The alignment between the DM and wavefront sensor (WFS)…
SynIM: a high-performance GPU-accelerated Python library for synthetic interaction and tomographic reconstruction matrices in next-generation adaptive optics
Guido Agapito, Fabio Rossi, Alfio Puglisi
Next-generation Adaptive Optics (AO) systems for 8-40m class telescopes, such as MORFEO (ELT) and MAVIS (VLT), demand high calibration accuracy. Controlling thousands of actuators…
