介绍了临边观测模式的探测原理及其特点, 给出了美国、欧洲等发达国家关于临边成像光谱仪的研究状况, 并列出了各临边成像光谱仪的核心设计方案及具体的技术指标。最后, 介绍了国内唯一一例临边成像光谱仪的开展情况, 包括设计方案到技术指标。通过对比分析国内外临边成像光谱仪的研究进展, 为我国进一步提高临边成像光谱仪的性能及技术指标提供了理论基础。

The methods and characteristics of limb viewing are introduced, and the research progress of limb imaging spectrometers is discribed. Then, the technical indexes of limb imaging spectrometers in the developed countries in America and Europe are compared and analyzed. Finally, the development situation of our country about the limb imaging spectrometers is introduced. Through comparative analysis of the research progress of limb imaging spectrometers at home and abroad, it provides the theoretical background basis for our country to further improve the performance and technical index of limb imaging spectrometers.
