Efficient implementation of pseudo open loop control for adaptive optics on Extremely Large Telescopes
Alastair Basden, David Jenkins, Tim Morris +2
Closed-loop adaptive optics systems which use minimum mean square error wavefront reconstruction require the computation of pseudo open loop wavefront slopes. These techniques inco…
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…
Turbulence velocity profiling for high sensitivity and vertical-resolution atmospheric characterization with Stereo-SCIDAR
J. Osborn, T. Butterley, M. J. Townson +3
As telescopes become larger, into the era of ~40 m Extremely Large Telescopes, the high- resolution vertical profile of the optical turbulence strength is critical for the validati…
Scintillation correction for astronomical photometry on large and extremely large telescopes with tomographic atmospheric reconstruction
James Osborn
We describe a new concept to correct for scintillation noise on high-precision photometry in large and extremely large telescopes using telemetry data from adaptive optics (AO) sys…
Open-loop tomography with artificial neural networks on CANARY: on-sky results
J. Osborn, F. J. De Cos Juez, D. Guzman +11
We present recent results from the initial testing of an Artificial Neural Network (ANN) based tomographic reconstructor Complex Atmospheric Reconstructor based on Machine lEarNing…
