Paper Abstract

Perspective imaging of laser guide stars leads to their elongation. This effect is significant in future large telescopes, where many such beacons are necessary. Solutions to these problems include mechanical or electronic movement at the sensing devices, optical separation of the reference sources and more. Another solution is to shift the burden of analysis to the lasers and create a pattern which suffers less from perspective elongation when scattered back onto the detectors. Finally, different analysis methods can then be employed to solve for the wave front tomographically from this projected pattern.
