Durham adaptive optics real-time controller (2010)
Journal Article

The Durham adaptive optics (AO) real-time controller was initially a proof of concept design for a generic AO control system. It has since been developed into a modern and powerful central-processing-unit-based real-time control system, capable of us... Read More about Durham adaptive optics real-time controller.

The EAGLE instrument for the European Extremely Large Telescope is a multi-object integral field unit spectrograph that uses a multi-object adaptive optics (AO) system for wavefront correction of interesting lines of sight. We present a Monte Carlo A... Read More about Considerations for EAGLE from Monte Carlo adaptive optics simulation.

Durham extremely large telescope adaptive optics simulation platform (2007)
Journal Article

Adaptive optics systems are essential on all large telescopes for which image quality is important. These are complex systems with many design parameters requiring optimization before good performance can be achieved. The simulation of adaptive optic...

Performance modeling of a wide-field ground-layer adaptive optics system (2006)
Journal Article
Andersen, D., Stoesz, J., Morris, S., Lloyd-Hart, M., Crampton, D., Butterley, T., …Wilson, R. (2006). Performance modeling of a wide-field ground-layer adaptive optics system. Publications of the Astronomical Society of the Pacific, 118(849), 1574-1590. https://doi.org/10.1086/509266

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, relatively low order deformable mirror to correct the wave-front errors from...

WIde-field adaptive optics correction using a single rotating laser guide star (2006)
Journal Article

Wave-front sensing from artificial beacons is normally performed by formation of a focused spot in the atmosphere and sensing of the wave-front distortions produced during the beam's return passage. We propose an alternative method that senses the di... Read More about Laser beacon wave-front sensing without focal anisoplanatism.

Wavefront correction using a self-referencing phase conjugation system based on a Zernike cell (2001)
