OH-airglow Suppressor (OHS), one of the first observational instruments of Subaru telescope, has been developed for three years. Test observations for performance verification and development of the multi-objects feeding system using fibers also have been done. Followings are the abstracts of this research work.・The throughput of 40% with an airglow-suppression factor of 1/25, yielding the 〜1.2 mag gain of the OHS, are verified using the results of the test observations. The OHS is operated as a common instrument of the Subaru telescope from this fiscal year. Many scripts and commands have been prepared to support the observation and the data reduction.・Spectroscopic results of QSOs at z〜5 obtained during the test observation runs of the OHS are combined with other archival data, such as Sloan Digital Sky Survey newly opened to the public. The evolution of iron emission-lines of QSOs from the local to the distant universe are studied and published.・Spectra of 16 radio galaxies at z〜2.3 are also successfully obtained during the test observation runs. The nature of these objects are studied and will be published soon.・ Multi-XY stage with 16 probes for the multi-objects feeding system of the OHS was fabricated. The control software and the algorithm for the optimum arrangement of the probes have been developed.・The first trial piece of the fiber bundle using tapered-fibers had many troubles. The second piece, in which selfoc lenses are attached to both ends of the fibers, was assembled by myself. It will be installed in the OHS and tested in March.The basic technical problems have been solved by this research work. The multi-object spectroscopy mode of the OHS will be improved through the test on the Nasmyth platform of the Subaru telescope and the following test observation.

OH-气辉抑制器（OHS）是斯巴鲁望远镜最早的观测仪器之一，已经研发了三年。还完成了使用纤维的多物体馈送系统的性能验证和开发的测试观察。以下是这项研究工作的摘要。 ・使用测试观察结果验证了 40% 的吞吐量和 1/25 的气辉抑制因子，产生〜1.2 mag 增益的 OHS。从本财年开始，OHS 将作为斯巴鲁望远镜的通用仪器运行。已经准备了许多脚本和命令来支持观测和数据缩减。 ・在 OHS 测试观测运行期间获得的 z〜5 处 QSO 的光谱结果与其他档案数据相结合，例如新向公众开放的斯隆数字巡天数据。研究并发表了QSO从本地宇宙到遥远宇宙的铁发射线的演化。 ・在测试观测过程中还成功获得了z〜2.3的16个射电星系的光谱。这些物体的性质正在研究中，并将很快发表。 ・ 为 OHS 的多物体供给系统制作了带有 16 个探头的多 XY 平台。控制软件和探头最佳布置的算法已经开发出来。 ・使用锥形光纤的光纤束的第一个试件遇到了很多麻烦。第二件是我自己组装的，其中自聚焦透镜固定在光纤的两端。将于3月份在OHS安装并进行测试。本次研究工作已经解决了基本技术问题。通过在斯巴鲁望远镜Nasmyth平台上的测试以及后续的测试观测，OHS的多目标光谱模式将得到改进。
