Abstract

Ground Layer Adaptive Optics (GLAO) is a relatively novel form of AO designed to provide image improvements over fields of view of ~10' or greater. A representative range of GLAO instrumentation projects from 4m to 42m are summarised. A related form of wide field AO is Multi-Object Adaptive Optics (MOAO). Here, much higher correction is required, but only for sparsely distributed "islands". The correction is applied in open-loop, and this feature, plus the high accuracy, wide field tomography required, mean that MOAO involves considerable technological development. Several pathfinders, as well as actual MOAO facility projects, are underway, and are surveyed here.
