Abstract
SUBARU telescope with 8.2 m diameter is being constructed atop Mauna Kea in the Hawaii island. It employs the thin-meniscus primary mirror that is supported by 260 actuators, providing the almost perfect surface figure for near infrared imaging. The atmospheric turbulence is now the dominant origin of image degradation. Therefore, the adaptive optics (hereafter AO) system is essential equipment for large ground telescopes.
