Abstract
We have tested and confirmed the proper functioning of our solution to the MCAO partial illumination issue in the context of the LINC-NIRVANA (LN) MCAO module, both in the laboratory and on-sky. We present the results in this paper. Availability of direct AO-telemetry for individual layers from the LN MCAO system can be potentially used to improve not only the stability of the independent AO loops, but also the wavefront sensor efficiency. We introduce this idea, called "wind-predictive wavefront control."
