本文介绍了SDSS-V本地体积映射（LVM）望远镜系统的建设，测试和调试的最新情况。LVM是构成第五代斯隆数字巡天的三个巡天之一，它将采用一个由四个16厘米望远镜组成的协调网络，为Las Campanas天文台的三个光纤光谱仪提供数据。目标是在360-980 nm波长范围内以37”空间分辨率和R~4000光谱分辨率绘制银河平面约2500平方度的光谱图。LVM还将瞄准麦哲伦云和其他本星系群星系。四个LVM望远镜中的每一个都由一个alt-alt配置的双镜恒铁仪组成，为光学试验板供电。这为基于光纤的积分场单元（IFU）产生了固定、稳定的焦平面。其中一台望远镜负责科学使用说明书（IFU），另外两台望远镜则观测相邻的磁场，以校准地冠辐射。第四台望远镜对明亮的恒星进行快速观测，以补偿大地吸收。光谱仪的入口狭缝散布在所有三种类型望远镜的光纤中，产生真正同时的科学和校准曝光。我们总结了望远镜系统的最终设计，并报告其建设，调整和实验室测试。我们还描述了我们预计于2022年底在LCO进行调试的部署计划。
This paper presents an update on the construction, testing, and commissioning of the SDSS-V Local Volume Mapper (LVM) telescope system. LVM is one of three surveys that form the fifth generation of the Sloan Digital Sky Survey, and it will employ a coordinated network of four, 16-cm telescopes feeding three fiber spectrographs at the Las Campanas Observatory. The goal is to spectrally map approximately 2500 square degrees of the Galactic plane with 37” spatial resolution and R~4000 spectral resolution over the wavelength range 360-980 nm. LVM will also target the Magellanic Clouds and other Local Group galaxies. Each of the four LVM telescopes consists of a two-mirror siderostat in alt-alt configuration feeding an optical breadboard. This produces a fixed, stable focal plane for the fiber-based Integral Field Unit (IFU). One telescope hosts the science IFU, while two others observe adjacent fields to calibrate geocoronal emission. The fourth telescope makes rapid observations of bright stars to compensate telluric absorption. The entrance slits of the spectrographs intersperse the fibers from all three types of telescope, producing truly simultaneous science and calibration exposures. We summarize the final design of the telescope system and report on its construction, alignment and testing in the laboratory. We also describe our deployment plan for commissioning at LCO, anticipated for late 2022.
