摘要:

空间探测光栅光谱仪是指利用光栅作为主色散元件在卫星轨道上对目标探测的光谱仪。阐述了用于空间探测的光栅光谱仪国内外最新发展状况,根据最新的空间探测光栅光谱仪的结构和技术指标,分析了空间光栅光谱仪的应用范围和发展方向。应用范围主要是空间环境探测和对地观测。其中空间环境主要关注电离层、臭氧层和温室气体的总量及廓线,对地观测主要是获得图谱合一的地球表面参数,在得到二维图像信息的同时,增加了一维光谱信息,使得信息量大大增加。最新的发展方向是探测谱段向紫外和红外延伸,系统覆盖更大的视场角,空间分辨率逐步提高。结合光谱仪系统可靠性高的优点,空间光栅光谱仪非常适于空间和地面环境的探测。

Abstract:

The grating spectrometer for space detection is a kind of spectrometer based on the grating dispersing which works on the satellite track. The recent development of grating spectrometer for space detecting is elaborated. Several kinds of advanced grating spectrometer’s structure and technical specification are introduced, and the latest development and application of grating spectrometer for space detection are analyzed. Latest application includes detection of the space atmosphere environment and the surface of earth, focus on ionosphere, ozone and greenhouse gas columns and profiles, acquiring the image and spectrum of earth surface simultaneously, which acquires more data than before. The latest development is to detect ultraviolet and infrared spectrum, which cover a larger field of view, and improve the spatial resolution. Combined with the advantages of high reliability of the system, grating spectrometer is very suitable for detecting space and terrestrial environment.

Key words: grating, spectrometer, space detection, spatial environment, resolution
