Durham adaptive optics real-time controller (2010)
Journal Article
Basden, A., Geng, D., Myers, R., & Younger, E. (2010). Durham adaptive optics real-time controller. Applied optics, 49(32), 6354-6363. https://doi.org/10.1364/ao.49.006354

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.

Considerations for EAGLE from Monte Carlo adaptive optics simulation (2010)
Journal Article
Basden, A., Myers, R., & Butterley, T. (2010). Considerations for EAGLE from Monte Carlo adaptive optics simulation. Applied optics, 49(31), G1-G8. https://doi.org/10.1364/ao.49.0000g1

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
Basden, A., Butterley, T., Myers, R., & Wilson, R. (2007). Durham extremely large telescope adaptive optics simulation platform. Applied optics, 46(7), 1089-1098. https://doi.org/10.1364/ao.46.001089

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
Morris, T., & Myers, R. (2006). WIde-field adaptive optics correction using a single rotating laser guide star. Monthly Notices of the Royal Astronomical Society, 370(4), 1783-1789. https://doi.org/10.1111/j.1365-2966.2006.10588.x

The problem of providing Adaptive Optics (AO) correction over a wide field of view is one that can be alleviated by using multiple conjugate AO (MCAO), or a low-altitude Laser Guide Star (LGS) that is projected to an altitude below any high layer tur...
