LOLAS: an optical turbulence profiler in the atmospheric boundary layer with extreme altitude-resolution
R. Avila, J. L. Aviles, R. W. Wilson +3
We report the development and first results of an instrument called Low Layer Scidar (LOLAS) which is aimed at the measurement of optical-turbulence profiles in the atmospheric bou…
A method of estimating time scales of atmospheric piston and its application at DomeC (Antarctica)
A. Kellerer, M. Sarazin, T. Butterley +1
Temporal fluctuations of the atmospheric piston are critical for interferometers as they determine their sensitivity. We characterize an instrumental set-up, termed the piston scop…
The Durham ELT adaptive optics simulation platform
Alastair Basden, Timothy Butterley, Richard Myers +1
Adaptive optics systems are essential on all large telescopes where image quality is important. These are complex systems with many design parameters requiring optimisation before…
Performance Modeling of a Wide Field Ground Layer Adaptive Optics System
D. Andersen, J. Stoesz, S. Morris +11
Using five independent analytic and Monte Carlo simulation codes, we have studied the performance of wide field ground layer adaptive optics (GLAO), which can use a single, relativ…
A Shack-Hartmann wavefront sensor projected onto the sky with reduced focal anisoplanatism
T. Butterley, G. D. Love, R. W. Wilson +2
A method for producing a laser guide star wavefront sensor for adaptive optics with reduced focal anisoplanatism is presented. A theoretical analysis and numerical simulations have…
Acceleration of adaptive optics simulations using programmable logic
A. G. Basden, F. Assemat, T. Butterley +3
Numerical Simulation is an essential part of the design and optimisation of astronomical adaptive optics systems. Simulations of adaptive optics are computationally expensive and t…
