Adaptive optics corrections of scintillations of Hermite-Gaussian modes in an oceanic medium.

Applied Optics, 2020
Adaptive optics correction of the scintillation index is found when Hermite-Gaussian laser beams are used in oceanic turbulence. Adaptive optics filter functions are used to find how the tilt, focus, astigmatism, coma, and total correction will behave ...

Adaptive optics and multi-conjugate adaptive optics with the VTT [PDF]

Astronomische Nachrichten, 2002
We are currently developing adaptive optics (AO) system with a multi-conjugate extension for the German solar vacuum tower telescope (VTT) at the Teide Observatory on Tenerife.Multi-conjugate adaptive optics (MCAO) is a technique for increasing the field of view by compensating atmospheric turbulence along several, adjacent lines of sight.

Sensorless adaptive optics for optical communications

Free-Space Laser Communications XXXIII, 2021
Mitigation of turbulence-induced disturbances is crucial for high data rate optical links in the atmosphere. Sensorless adaptive optics, based on the optimization of the coupling in a single mode fiber, is a promising solution as it circumvents the limitations of conventional wavefront sensing in strong perturbations.
