Estimating Atmospheric Wind Speeds From Gemini Planet Imager AO Telemetry
Zhenxi Du, Saavidra Perera, Daniel Levinstein +6
The Earth's atmosphere is comprised of turbulent layers that result in speckled and blurry images from ground-based visible and infrared observations. Adaptive Optics (AO) systems…
SHIMM: A Versatile Seeing Monitor for Astronomy
Saavidra Perera, Richard W. Wilson, Tim Butterley +3
Characterisation of atmospheric optical turbulence is crucial for the design and operation of modern ground-based optical telescopes. In particular, the effective application of ad…
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…
Reference Optical Turbulence and Wind Profiles for Single Conjugate and Extreme Adaptive Optics
O. J. D. Farley
We present a simple method of extracting a small number of reference optical turbulence and wind profiles from a large dataset for single conjugate and extreme adaptive optics simu…
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…
Limitations imposed by optical turbulence profile structure and evolution on tomographic reconstruction for the ELT
O. J. D. Farley, J. Osborn, T. Morris +4
The performance of tomographic adaptive optics systems is intrinsically linked to the vertical profile of optical turbulence. Firstly, a sufficient number of discrete turbulent lay…
