Demonstrating 24-hour continuous vertical monitoring of atmospheric optical turbulence
Ryan Griffiths, James Osborn, Ollie Farley +3
We report what is believed to be the first example of fully continuous, 24-hour vertical monitoring of atmospheric optical turbulence. This is achieved using a novel instrument, th…
Astrosat: Forecasting satellite transits for optical astronomical observations
James Osborn, Laurence Blacketer, Matthew J. Townson +1
The impact of large-scale constellations of satellites, is a concern for ground-based astronomers. In recent years there has been a significant increase in the number of satellites…
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…
Representative optical turbulence profiles for ESO Paranal by hierarchical clustering
O. J. D. Farley, J. Osborn, T. Morris +5
Knowledge of the optical turbulence profile is important in adaptive optics (AO) systems, particularly tomographic AO systems such as those to be employed by the next generation of…
Generating Artificial Reference Images for Open Loop Correlation Wavefront Sensors
M. J. Townson, G. D Love, C. D. Saunter
Shack-Hartmann wavefront sensors for both solar and laser guide star adaptive optics (with elongated spots) need to observe extended objects. Correlation techniques have been succe…
