中文摘要	在几种适合用来对面天体进行分光测量的仪器中，积分视场光谱仪(Integral Field Spectrograph，IFS) 因能同时获得二维视场光谱信息而备受关注，经过近三十年的发展业已成为大中型望远镜的标准终端设备，广泛应用于各大天文学分支。我国2.4米光学望远镜以及LAMOST相继建成，可以考虑在2.4米望远镜上配备IFS开展一系列工作，特别是对LAMOST发现的某些新的天体做进一步研究。基于对IFS的初步研究，作者决定先在实验室中进行光纤式积分视场光谱仪实验，取得一定进展后再将实验设备用于云南天文台2.4米望远镜，对特定的天体进行测量，从而为科学级IFS的研制积累必要的经验。目前已经完成实验设备研制、光路调试、光谱定标以及太阳光的吸收谱测量等工作，并在2.4米望远镜上对猎户座星云进行了实验观测，获得了电离氧发射线等初步数据，并发现了光纤制作、光谱仪改造等方面的问题，这些将为更好地开展下一步工作打下基础。引言部分介绍了包括IFS在内的多种常见二维光谱技术，并对各自优缺点进行讨论；第一章概述了四种不同的积分视场光谱仪技术；第二章中列举了大量实例来说明积分视场光谱仪在天文学中的应用价值；文章的第三章、第四章、第五章详细介绍了光纤式积分视场光谱仪实验，包括实验设备的设计与制作、系统的实验室调试以及实地观测等内容，文章的最后对上述内容做了总结，指出本文的意义所在。
英文摘要	There are some kinds of equipments can be used to study the expand astronomical objects and the Integral Field Spectrograph (IFS) is a popular and powerful technique with great potential for the further understanding of these science cases. It can provide two-dimensional spatial and one spectral information for spectroscopic observation simultaneously. At this period Lijiang 2.4 meters Telescope and LAMOST (The Large Sky Area Multi-Object Fiber Spectroscopic Telescope) had been build, it is good news for the IFS. There are so many kinds of amazing science cases for the 2.4 meters telescope if it has IFS, especially when the Lijiang telescope cooperates with the LAMOST. Therefore the author conceives the ideal of providing IFS for Lijiang 2.4m Telescope. An experiment of IFS on the laboratory is needed at the first step and the equipment for this experimental study has been prepared. They also have done some tests for the IFS system on the laboratory such as optics adjustment, spectrum calibration and solar absorption spectrum probe. And this instrument has been attached to the 2.4m telescope for the observation of Orion Nebula. In the introduction, the over view of modern 2D Spectrograph technology were briefly introduced at the first time and discussed the advantages and disadvantages of each other. In chapter 1，four major IFS methods had been summarized. There are some application cases of IFS for the astronomical researching in chapter 2. The main contents of chapter 3, chapter 4 and chapter 5 are the experiment of fiber integral field spectrograph. A conclusion of this paper has fingered out what the means of this experiment.
