Physics-based model of the adaptive-optics corrected point-spread-function
Romain Fétick, Thierry Fusco, Benoit Neichel +8
Context. Adaptive optics (AO) systems greatly increase the resolution of large telescopes, but produce complex point spread function (PSF) shapes, varying in time and across the fi…
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…
Optimizing the accuracy and efficiency of optical turbulence profiling using adaptive optics telemetry for extremely large telescopes
Douglas J Laidlaw, James Osborn, Timothy J Morris +8
Advanced adaptive optics (AO) instruments on ground-based telescopes require accurate knowledge of the atmospheric turbulence strength as a function of altitude. This information a…
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…
