空间紫外光学遥感技术是除可见、近红外、热红外和微波遥感以外的一个具有突出优势的遥感领域，全球气候变化研究是目前国际上空间紫外-真空紫外光学遥感的热点课题。本文对空间紫外光学遥感的作用、国内外研究现状及发展趋势进行了综述和分析。介绍了一组紫外光学遥感仪器的功能和特点，给出了它们的主要性能参数；指出我国目前的工作重点是推进星载紫外光谱遥感仪器的应用、积累空间探测数据、建立反演算法等；而未来发展目标将是研制集天底、临边和掩星成像探测于一体的新一代紫外成像探测仪器，高精度观测全天候的整层大气密度和臭氧的三维分布，实时监测大气组分及化学成分（如O₂、N₂、NO、OH和O₃）的变化及变化趋势，以及进一步拓展我国紫外光学遥感仪器的应用领域。

Space UV optical remote sensing technology and development

Space ultraviolet optical remote sensing is a preponderant field besides visible light, near infrared, thermal infrared and microwave remote sensing technologies. Now, research on change of global circumstances by space ultraviolet and vacuum ultraviolet optical remote sensing technique is a hot topic in the world. In this paper, the function, status and development of space ultraviolet optical remote sensing are reviewed, and the characteristics and performance parameters of several kinds of space UV remote sensing instruments are introduced. Finally, it indicates that the key points for UV remote sensing at present are applications of the space borne ultraviolet optical remote sensing instruments, accumulations of space detection data, and establishment of reversion algorithm. This paper suggests that the objectives of the UV optical remote sensing in future are to develop the instruments with nadir, limb and obscuration function synchronously, detect the threedimensional ozone in high accuracy, all weather and whole atmosphere, monitor the change and changing trend of atmospheric components in real time, and to expand the application scopes for space ultraviolet remote sensing instruments. 
