Paper Abstract
The Large Synoptic Survey Telescope will map out the dark matter in the universe and is scheduled to see "first light" in
2014. This telescope will require active correction of its mirrors to remove the aberrations that arise from changing
gravitational force vectors and from thermal drifts in the telescope during observational runs. In this article we present a
comprehensive evaluation of a Shack-Hartmann wavefront sensor and reconstruction algorithm which is capable of
meeting the unique challenges associated with this wide field-of-view survey telescope. The advantages of this technique
over other potential wavefront sensing technologies are discussed and the potential problems encountered with this
approach are analyzed and solutions to these problems presented.
