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.
