ULTIMATE-斯巴鲁自适应光学研究实验（ULTIMATE-START）是斯巴鲁望远镜上的激光层析成像AO项目。该项目计划在NIR波段实现高Strehl比率AO校正，在600 nm以上的可见光波段实现中等AO校正。一个由4颗激光引导星（LGS）组成的卫星将从次镜后面的激光发射望远镜发射。将在当前设施LGS AO系统AO 188后面安装带有4个32$times$32 Shack-Hartmann波前传感器的断层成像波前传感单元。AO 188的变形镜将升级为64$times$64元DM。校正后的光将通过正在开发的红外侧Nasmyth聚焦仪器的光束切换光学器件馈送到光学积分场摄谱仪3DII和近红外相机和摄谱仪IRCS。激光发射系统和波前传感单元的第一次光计划在2021年。
ULTIMATE-Subaru Tomography Adaptive optics Research experimenT (ULTIMATE-START) is a laser tomography AO project on the Subaru telescope. The project is planned to achieve high Strehl Ratio AO correction in NIR bands, and moderate AO correction in visible bands above 600nm. An asterism of 4 laser guide stars (LGSs) will be launched from the laser launching telescope behind the secondary mirror. The tomography wavefront sensing unit with four 32$times$32 Shack-Hartmann wavefront sensors will be installed behind the current facility LGS AO system, AO188. The deformable mirror of AO188 will be upgraded to a 64$times$64 element DM. The corrected light will be fed to the optical integral field spectrograph, 3DII, and NIR camera and spectrograph, IRCS, through a beam switching optics for IR-side Nasmyth focus instruments under development. The first light of the laser launching system and wavefront sensing unit is planned in 2021.
