Abstract
The techniques proposed in literature in order to correct the scientific object image motion using Laser Guide Star tilt measurements are briefly reviewed. Emphasis is given on comparison among the basic ideas of the various techniques. An analysis of these ideas allows to identify the limitations and error sources of different techniques, and to discuss their performances in terms of achieved tip-tilt measurement accuracy. The use of multiple laser guide star wavefront sensing schemes is considered as a way to increase the performances of the analyzed techniques.
