Entering into the Wide Field Adaptive Optics Era on Maunakea
Gaetano Sivo, John Blakeslee, Jennifer Lotz +32
As part of the National Science Foundation funded "Gemini in the Era of MultiMessenger Astronomy" (GEMMA) program, Gemini Observatory is developing GNAO, a widefield adaptive optic…
Identifying optical turbulence profiles for realistic tomographic error in adaptive optics
O. J. D. Farley, J. Osborn, T. Morris +4
For extremely large telescopes, adaptive optics will be required to correct the Earth's turbulent atmosphere. The performance of tomographic adaptive optics is strongly dependent o…
Adaptive optics with programmable Fourier-based wavefront sensors: a spatial light modulator approach to the LOOPS testbed
Pierre Janin-Potiron, Vincent Chambouleyron, Lauren Schatz +10
Wavefront sensors encode phase information of an incoming wavefront into an intensity pattern that can be measured on a camera. Several kinds of wavefront sensors (WFS) are used in…
PRIME: Psf Reconstruction and Identification for Multiple sources characterization Enhancement. Application to Keck NIRC2 imager
O. Beltramo-Martin, C. M. Correia, S. Ragland +4
In order to enhance accuracy of astrophysical estimates obtained on Adaptive-optics (AO) images, such as photometry and astrometry, we investigate a new concept to constrain the Po…
Kernel formalism applied to Fourier based wave front sensing in presence of residual phases
Olivier Fauvarque, Pierre Janin-Potiron, Carlos Correia +5
In this paper, we describe Fourier-based Wave Front Sensors (WFS) as linear integral operators, characterized by their Kernel. In a first part, we derive the dependency of this qua…
PEPITO: atmospheric Profiling from short-Exposure focalPlane Images in seeing-limiTed mOde
Olivier Beltramo-Martin, Nazim A. Bharmal, Carlos M. Correia
Atmospheric profiling is a requirement for controlling wide-field Adaptive Optics (AO) instruments, analyzing the AO performance with respect to the observing conditions and predic…
