介绍了斯巴鲁望远镜的激光导星自适应光学（AO188）系统。该系统将安装在 Subaru 8 m 望远镜的 IR Nasmyth 平台上，而当前具有 36 个元件的 AO 系统则在卡塞格伦焦点上运行。新的 AO 系统具有 188 元件波前曲率传感器、光子计数 APD 模块和 188 元件双压电晶片镜。激光导星系统在Nasmyth平台上配备了4.5 W固态和频激光器。 50厘米口径的激光发射望远镜将安装在副镜后面。激光束将使用光子晶体单模光纤电缆传输到激光发射望远镜。带有AO系统的仪器是IRCS，红外相机和光谱仪，已用于卡塞格伦AO系统和新仪器HiCIAO，用于太阳系外行星探测的高动态范围红外相机。 AO 系统的第一盏灯计划于 2006 年推出。
The laser guide star adaptive optics (AO188) system for Subaru Telescope is presented. The system will be installed at the IR Nasmyth platform of Subaru 8 m telescope, whereas the current AO system with 36 elements is operating at the Cassegrain focus. The new AO system has a 188 element wavefront curvature sensor with photon counting APD modules and 188 element bimorph mirror. The laser guide star system has a 4.5 W solid state sum-frequency laser on the Nasmyth platform. The laser launching telescope with 50 cm aperture will be installed at behind the secondary mirror. The laser beam will be transferred to the laser launching telescope using photonic crystal single mode fiber cable. The instrument with the AO system is IRCS, infrared camera and spectrograph which has been used for Cassegrain AO system and new instrument, HiCIAO, high dynamic range infrared camera for exsolar planet detection. The first light of the AO system is planned in 2006.
