Tomographic wavefront error using multi-LGS constellation sensed with Shack-Hartmann wavefront sensors.

Noise effects induced by laser guide star (LGS) elongation have to be considered globally in a multi-LGS tomographic reconstruction analysis. This allows a fine estimation of performance and the comparison of different launching options. We present a modal analysis of the wavefront error with Shack-Hartmann wavefront sensors based on quasi-analytical matrix… CONTINUE READING
