Study of centroiding algorithms to optimize Shack-Hartmann WFS in the context of ELTs
1st AO4ELT conference - Adaptive Optics for Extremely Large Telescopes
Along with the expected ELTs comes the diversification of Adaptive Optics (AO) systems. Most AO are beginning to make extensive use of laser guide stars (LGS), to increase sky coverage and produce a bright beacon in order to reduce wavefront measurement errors and improve performance. However, because of the larger size of the next generation of telescopes, the elongation seen in a Shack-Hartmann Wavefront Sensor is larger, i.e up to 7" for a 30m telescope. With such an elongation, both photondoi:10.1051/ao4elt/201005004 fatcat:gmjqxsuulzh5zipexois23irlu
