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)因为能同时获得面源的光谱信息而备受关注. 基于对IFS的初步研究, 在实验室中进行光纤式IFS实验, 取得一定进展后再将实验设备用于云南天文台2.4 m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 m望远镜上对特定目标进行了实验观测, 获得了初步数据, 发现了光纤制作等方面的一些问题, 为下一步工作奠定基础 |

Among several types of instruments used to study extended astronomical objects the Integral Field Spectroscopy has been received wide attention because of its capability of obtaining spectra across the surface of an extended object simultaneously. We aim to build an Integral Field Spectrograph (IFS) for the Lijiang 2. 4 m Telescope of the Yunnan Observatory. We decide to carry out an experiment of IFS in laboratory. As the first step, we have also finished some tests with the experimental IFS system including optical adjustment, spectral calibration, and measurement of some solar absorption-line spectra. We have subsequently attached this instrument to the 2. 4 m telescope and have obtained some useful data. Through the experiment we have found some problems with the manufacturing of the optical fibers used. These should provide the basis of our work ahead |
