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…
Characterisation of the ground layer of turbulence at Paranal using a robotic SLODAR system
T. Butterley, R. W. Wilson, M. Sarazin +3
We describe the implementation of a robotic SLODAR instrument at the Cerro Paranal observatory. The instrument measures the vertical profile of the optical atmospheric turbulence s…
Atmospheric Scintillation Noise in Ground-Based Exoplanet Photometry
D. Föhring, R. W. Wilson, J. Osborn +1
Atmospheric scintillation caused by optical turbulence in the Earth's atmosphere can be the dominant source of noise in ground-based photometric observations of bright targets, whi…
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…
Experience with wavefront sensor and deformable mirror interfaces for wide-field adaptive optics systems
A. G. Basden, D. Atkinson, N. A. Bharmal +56
Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extr…
Atmospheric Scintillation in Astronomical Photometry
J. Osborn, D. Föhring, V. S. Dhillon +1
Scintillation noise due to the Earth's turbulent atmosphere can be a dominant noise source in high-precision astronomical photometry when observing bright targets from the ground.…
