标题： Prime Focus Spectrograph (PFS) for the Subaru Telescope: Overview, recent progress, and future perspectives

摘要： PFS（Prime Focus Spectrograph），即8.2米斯巴鲁望远镜上的下一代台面仪器，是一款具有非常宽视场、高度多路复用的光学和近红外光谱仪。利用斯巴鲁望远镜的主焦点，2394根可重构光纤将在1.3度视场内分布。该光谱仪设计有蓝光、红光和近红外三个相机手臂，可在一次曝光中以~1.6-2.7Å的分辨率同时观测从380纳米到1260纳米的光谱。该项目由Kavli IPMU发起，并由国际团队合作开发。项目目前进入建设阶段，计划在2017-2018年进行系统集成，并随后在2018-2019年开展工程运行。本文综述了该仪器的概况、当前项目状态以及未来的发展方向。 显示英文摘要

摘要： PFS (Prime Focus Spectrograph), a next generation facility instrument on the 8.2-meter Subaru Telescope, is a very wide-field, massively multiplexed, optical and near-infrared spectrograph. Exploiting the Subaru prime focus, 2394 reconfigurable fibers will be distributed over the 1.3 deg field of view. The spectrograph has been designed with 3 arms of blue, red, and near-infrared cameras to simultaneously observe spectra from 380nm to 1260nm in one exposure at a resolution of ~1.6-2.7A. An international collaboration is developing this instrument under the initiative of Kavli IPMU. The project is now going into the construction phase aiming at undertaking system integration in 2017-2018 and subsequently carrying out engineering operations in 2018-2019. This article gives an overview of the instrument, current project status and future paths forward.
