Adaptive optics is a powerful new technique used to sharpen telescope images blurred by
the Earth's atmosphere. This authoritative book is the first dedicated to the use of adaptive …

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 …

Adaptive optics is a prime example of how progress in observational astronomy can be
driven by technological developments. At many observatories it is now considered to be part …

A general formulation is given for the derivation of theoretical temporal power spectra of
quantities related to turbulent wave-front phase. These temporal power spectra and their …

The use of laser beacons to create artificial reference stars for adaptive optics has been
successfully demonstrated by several experiments (Fugate et al., 1991; Primmerman et al …

Since the year 2000, adaptive optics (AO) has seen the emergence of a variety of new
concepts addressing particular science needs; multiconjugate adaptive optics (MCAO) is …

The Gemini multiconjugate adaptive optics system (GeMS) at the Gemini South telescope in
Cerro Pachón is the first sodium-based multilaser guide star (LGS) adaptive optics system. It …

We propose an optimal approach for the phase reconstruction in a large field of view (FOV)
for multiconjugate adaptive optics. This optimal approach is based on a minimum-mean …

IMAGES formed by ground-based telescopes are marred by atmospheric'seeing9. The
plane wavefront from an unresolved star is distorted by continually changing turbulent …

Deconvolution is a necessary tool for the exploitation of a number of imaging instruments.
We describe a deconvolution method developed in a Bayesian framework in the context of …
