终极斯巴鲁是斯巴鲁望远镜的下一个大型设施仪器项目。我们将在地面层自适应光学系统（GLAO）的帮助下，开发一个14x14 arcmin宽视场近红外（1.0-2.5μm）成像仪和一个多目标光谱仪，它将在直径达~20 arcmin的宽视场上均匀地提高2倍的能见度。在斯巴鲁望远镜中等观测条件下，GLAO校正后的k波段空间分辨率约为0.2 arcsec FWHM。在TMT时代，ULTIMATE-Subaru将提供实现近红外宽视场和高空间分辨率观测的独特能力。本文介绍了该项目的总体情况，包括GLAO和近红外仪器的概念设计。我们还描述了斯巴鲁望远镜未来的宽视场策略，包括ULTIMATE-Subaru以及HSC和PFS。
ULTIMATE-Subaru is a next large facility instrument project at Subaru telescope. We will develop a 14x14 arcmin2wide-field near-infrared (1.0-2.5μm) imager and a multi-object spectrograph with the aid of a ground- layer adaptive optics system (GLAO), which will uniformly improve the seeing by a factor of 2 over a wide field of view up to ~20 arcmin in diameter. The expected spatial resolution by the GLAO correction is about 0.2 arcsec FWHM in K-band under moderate seeing conditions at Subaru telescope. ULTIMATE-Subaru will provide a unique capability to realize wide-field and high spatial resolution survey observations in near infrared in the era of TMT. In this paper, we introduce the project overview including the GLAO and near-infrared instrument conceptual design. We also describe the future wide-field strategy at Subaru telescope with ULTIMATE-Subaru together with HSC and PFS.
