我们目前的天空中的结果，从大视场的地面层自适应光学（GLAO）系统的夏威夷大学的2.2米望远镜的莫纳克亚。我们证明了在各种可见光条件下，在可见光波长的图像质量的改善。我们讨论了各种品质因数的增益，包括半峰全宽，等效噪声面积和环绕能量直径。这些增益和优点的数字在我们的GLAO科学案例的背景下进行了讨论。此外，我们提出了系统的图像质量误差预算，测量的主要误差项，以及它们对交付的焦平面图像的影响。
We present on-sky results from the wide field ground-layer adaptive optics (GLAO) system on the University of Hawaii 2.2-meter telescope on Maunakea. We demonstrate improvements in image quality at visible wavelengths under a variety of seeing conditions. We discuss the gains for a variety of figures of merit including the full-width at half-maximum, the equivalent noise area, and the encircled energy diameter. These gains and figures of merit are discussed in the context of our GLAO science cases. In addition, we present the system image quality error budget, measurements of the dominant error terms, and their impact on the delivered focal plane images.
