本文介绍了将于2012年1月发射到国际空间站的可见光和近红外光谱成像仪（VISI）的科学目标、仪器设计、测量原理和发展。VISI配备了快速光学系统，包括棱镜和高灵敏度CCD，以获得O（630 nm），OH Meinel波段（650 nm）和O2（0-0）大气波段（762 nm）波长的气辉发射。VISI有两个视场（FOV），向前45度和向后45度到最低点，以减去背景污染。当国际空间站在地球的夜晚一侧运行时，VISI的数据采集将以小于几秒钟的短曝光周期连续进行，然后提供空间分辨率优于50公里的气辉无缝线扫描图像。在制造VISI之后，我们通过光学和电气功能测试以及发射所需的环境测试来检查其性能。
We present the scientific targets, instrumental design, principle of measurement, and development of the Visible and near-Infrared Spectral Imager (VISI) which will be launched onto International Space Station (ISS) in January 2012. VISI is equipped with fast optics including a grism, and a high-sensitivity CCD to obtain airglow emissions at wavelengths of O (630 nm), OH Meinel band (650 nm) and O2 (0-0) atmospheric band (762 nm). VISI has two field-of-views (FOVs), 45 degrees forward and 45 degrees backward to nadir, to subtract background contaminations. The data acquisition of VISI will be continuously performed with short exposure cycle less than several seconds when ISS is orbiting in the night side of the earth, and then provide the seamless line scanning images of the airglows with a spatial resolution better than 50 km. After manufacturing VISI, we checked its performance though optical and electric function tests as well as environmental tests that are necessary to be launched.
