摘要：

The knowledge of the temporal evolution of a star wandering for a limited time interval (e.g., a fraction of a second) can be used to increase dramatically the sky coverage of a laser-beacon adaptive optics system. A technique to achieve such short-term tracking is described. The full sky coverage is easily achieved by using the whole telescope as a laser projector.
