摘　　要：超光谱成像技术由于能够同时获取目标的空间信息和光谱信息,显著提高了空间遥感技术对地物的探测和识别能力,在对地观测和深空探测领域具有广阔的应用前景。总结了星载超光谱成像技术近三十年来的国内外研究现状,对国内外典型超光谱成像仪的技术指标、技术特点和应用领域进行了论述。分析结果表明:高空间分辨率、高光谱分辨率是超光谱成像技术未来的发展趋势,offner光栅色散型超光谱成像仪是一个重要的发展方向。Hyperspectral imaging technique acquires spatial information and spectral information simultaneity, that improve obiects detected and distinguished capability of space remote sensing techniques markedly. It has extensive applied fore- ground in the fields of ground observed and deep space explored. This paper summarizes the developments of hyperspectral imaging techniques in detail domestically and abroad for last 30 years, and explains the specification, technical characteristics and applied fields of typical hyperspectral imagers. The result indicates that high spatial resolution and high spectral resolu tion is a developed trend of hyperspectral imaging techniques, offner grating dispersive hyperspectral imager is an important developed direction.
