Pathfinders to ELT AO at W.M. Keck Observatory


Peter Wizinowich


W.M. Keck Observatory


The Keck II AO system has been extremely productive scientifically with more than 300 refereed science papers including over 100 obtained with LGS AO. We will discuss lessons learned for ELT AO from the existing system and from the soon to be completed Keck I LGS AO system, as well as from pathfinder development efforts including a near-IR tip-tilt sensor, PSF reconstruction efforts and the Observatory’s next generation AO system.
