Shack-Hartmann wavefront sensing with elongated sodium laser beacons: centroiding versus matched filtering [PDF]
, 2006 We describe modeling and simulation results for the Thirty Meter Telescope on the degradation of sodium laser guide star Shack-Hartmann wavefront sensor measurement accuracy that will occur due to the spatial structure and temporal variations of the ...

The Anisoplanatic Point Spread Function in Adaptive Optics [PDF]
, 2006 The effects of anisoplanatism on the adaptive optics point spread function are investigated. A model is derived that combines observations of the guide star with an analytic formulation of anisoplanatism to generate predictions for the adaptive optics ...
