高光谱遥感由于"图谱合一"的技术特点,能够提供更加丰富的对地观测信息,是一种较为先进的探测技术,目前已应用到地球科学的各个方面.本文首先介绍了高光谱成像仪的成像特点,进而从航空高光谱和航天高光谱两个角度分别介绍了成像仪的工程应用概况.最后,根据近几年国内外的有关论文及研究报告,综述了国内外高光谱成像仪最新发展态势,重点介绍了天宫一号高光谱成像仪的研制技术情况,与目前国际上的在轨运行的卫星高光谱仪相比,其在空间分辨率、波谱范围和波段数目等成像技术参数上具有相当优势,是我国光谱仪技术发展的里程碑.

Hyperspectral sensing can provide richer information in earth observation, because of the technical characteristic of the combining image and spectrum. It has been applied to all aspects of the earth sciences, as a more advanced detection technology. Firstly, the author describes the imaging characteristics of hyperspectral imager, and then introduces engineering applications both in the aviation and aerospace. Finally, the author summarizes the latest development of hyperspectral imager according to the papers and research reports which published in major academic journals in domestic and foreign in recent years.
