The Enhanced Resolution Imager and Spectrograph for the VLT
R. Davies, O. Absil, G. Agapito +81
ERIS, the Enhanced Resolution Imager and Spectrograph, is an instrument that both extends and enhances the fundamental diffraction limited imaging and spectroscopy capability for t…
Optimal filtering techniques for the adaptive optics system of the LBT
G. Agapito, F. Quirós-Pacheco, P. Tesi +2
In this paper we will discuss the application of optimal filtering techniques for the adaptive optics system of the LBT telescope. We have studied the application of both Kalman an…
First on-sky results of ERIS at VLT
Kateryna Kravchenko, Yigit Dallilar, Olivier Absil +46
ERIS (Enhanced Resolution Imager and Spectrograph) is a new adaptive optics instrument installed at the Cassegrain focus of the VLT-UT4 telescope at the Paranal Observatory in Chil…
Optical calibration of large format adaptive mirrors
Runa Briguglio, Marco Xompero, Armando Riccardi
Adaptive (or deformable) mirrors are widely used as wavefront correctors in adaptive optics systems. The optical calibration of an adaptive mirror is a fundamental step during its…
The simulator of the VLT Deformable Secondary Mirror: a test tool for adaptive optics instruments for the Yepun-UT4 telescope
Runa Briguglio, Armando Riccardi, Luca Carbonaro +3
The Deformable Mirror Simulator (DMS) is an optical device reproducing the F/13 beam from the adaptive secondary mirror of the Very Large Telescope UT4. The system has been designe…
Bringing SOUL on sky
Enrico Pinna, Fabio Rossi, Alfio Puglisi +20
The SOUL project is upgrading the 4 SCAO systems of LBT, pushing the current guide star limits of about 2 magnitudes fainter thanks to Electron Multiplied CCD detector. This improv…
Slaving and disabling actuators with voice-coil adaptive mirrors
Armando Riccardi
Adaptive mirrors based on voice-coil technology have force actuators with an internal metrology to close a local loop for controlling its shape in position. When actuators are requ…
ERIS: revitalising an adaptive optics instrument for the VLT
Richard Davies, Simone Esposito, Hans Martin Schmid +63
ERIS is an instrument that will both extend and enhance the fundamental diffraction limited imaging and spectroscopy capability for the VLT. It will replace two instruments that ar…
Status of MagAO and review of astronomical science with visible light adaptive optics
Laird M. Close, Jared R. Males, Katie M. Morzinski +10
We review astronomical results in the visible (lambda <1 micron) with adaptive optics and note the status the MagAO system and the recent upgrade to visible camera's Simultaneous/S…
MagAO: Status and Science
Katie M. Morzinski, Laird M. Close, Jared R. Males +10
"MagAO" is the adaptive optics instrument at the Magellan Clay telescope at Las Campanas Observatory, Chile. MagAO has a 585-actuator adaptive secondary mirror and 1000-Hz pyramid…
The ERIS Adaptive Optics System
A. Riccardi, S. Esposito, G. Agapito +19
ERIS is the new AO instrument for VLT-UT4 led by a Consortium of Max-Planck Institut fuer Extraterrestrische Physik, UK-ATC, ETH-Zurich, ESO and INAF. The ERIS AO system provides N…
Direct imaging of exoplanets in the habitable zone with adaptive optics
Jared R. Males, Laird M. Close, Olivier Guyon +16
One of the primary goals of exoplanet science is to find and characterize habitable planets, and direct imaging will play a key role in this effort. Though imaging a true Earth ana…
MagAO: Status and on-sky performance of the Magellan adaptive optics system
Katie M. Morzinski, Laird M. Close, Jared R. Males +19
MagAO is the new adaptive optics system with visible-light and infrared science cameras, located on the 6.5-m Magellan "Clay" telescope at Las Campanas Observatory, Chile. The inst…
Into the Blue: AO Science with MagAO in the Visible
Laird M. Close, Jared R. Males, Katherine B. Follette +11
We review astronomical results in the visible (λ<1μm) with adaptive optics. Other than a brief period in the early 1990s, there has been little astronomical science done in the vis…
