Mitigating Tilt Anisoplanatism with the Slope Merging Method for Multi-Conjugate Adaptive Optics Systems

Large optical telescopes depend on adaptive optics for the real-time compensation of turbulence-induced wavefront aberrations. The performance of laser guide star based Multi-Conjugate Adaptive Optics systems is degraded by tilt anisoplanatism. In this paper we propose and derive a method for mitigating this effect, achieved by merging the measurements of natural and laser guide stars together. Th...
