After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

The discovery of the exoplanet Proxima b highlights the potential for the coming generation
of giant segmented mirror telescopes (GSMTs) to characterize terrestrial—potentially …

Dedicated tip–tilt loops are commonly implemented on adaptive optics (AO) systems. In
addition, a number of recent high-performance systems feature tip–tilt controllers that are …

Accurate astrometry is a key deliverable for the next generation of multiconjugate adaptive
optics (MCAO) systems. The MCAO-Assisted Visible Imager and Spectrograph (MAVIS) is …

We present in this paper an analysis of several tip-tilt on-sky data registered on adaptive
optics systems installed on different telescopes (Gemini South, William Herschel Telescope …

When high performance is expected, vibrations are becoming a burning issue in adaptive
optics systems. For mitigation of these vibrations, in this paper, we propose a method to …

Modern large telescopes are built based on the effectiveness of adaptive optics systems in
mitigating the detrimental effects of wavefront distortions on astronomical images. In …

Perturbation modelling and vibration compensation are key issues to reach better
performance in adaptive optics systems for VLTs and future ELTs. In this context, an LQG …

Linear quadratic Gaussian (LQG) control is an appealing control strategy to mitigate
disturbances in adaptive optics (AO) systems. The key of this method is to quickly and …

We propose a method to identify tip-tilt disturbance model for Linear Quadratic Gaussian
control. This identification method based on Levenberg–Marquardt method conducts with a …
