WebGround-layer adaptive optics (GLAO) promises a significant improvement in image width and energy concentration over atmospheric seeing in a relatively wide field by compensatingforlow-altitudeturbulence only. This approach, which is intermediate between full AO and seeing-limited observations, can benefit many WebTo obtain wider fields we also used multiple Lucky-Imaging guide stars in a configuration similar to a ground layer adaptive optics system. ... Adaptive optics has been used successfully for high-angular resolution imaging in the near-infrared on a large number of 5-10m class telescopes. However, it has not yet demonstrated routine diffraction ...
