摘　　要：相对可见光和短波红外谱段来说,在红外谱段进行高光谱遥感成像具有独特优势,特别是在资源勘查、地表环境监测、大气环境监测、军事侦察方面。尽管当前红外高光谱成像仪主要以机载为主,还未实现星载,然而国内外相关机构从未放弃推进红外高光谱遥感的星载化。文中首先分析了国内外典型的红外高光谱成像仪的设计、实现与技术指标,从光谱分辨率、空间分辨率、辐射分辨率三个核心指标总结了现有红外高光谱成像仪的技术特点、存在问题和解决途径。未来很长的一段时间内,红外精细分光、低暗电流焦平面探测器、低温光学与背景抑制仍然是红外高光谱成像仪研制所要解决的核心问题。在此基础上,文中重点介绍了在远距离气体探测方面的应用,并分析了其独特优势。最后,展望了红外高光谱成像技术的发展方向。Compared with the visible to short wave infrared spectrum,hyperspectral remote sensing imaging in the infrared spectrum has unique application advantages,especially in resource exploration,surface environment monitoring,atmospheric environment monitoring and military reconnaissance.Although the infrared hyperspectral imagers are mainly airborne at present,the domestic and foreign institutions have never given up promoting the spaceborne application of infrared hyperspectral remote sensing.Therefore,based on the detailed analysis of the design,implementation and specifications of the primary infrared hyperspectral imagers,this paper first summarizes the characteristics,existing problems and solutions of the current infrared hyperspectral imagers from the three key indexes of spectral resolution,spatial resolution and radiometric resolution.That is,breaking through the technologies of fine spectroscopy,high-sensitivity detectors,low-temperature optics and background radiation suppression are the main technical problems to be solved in the development of infrared hyperspectral imagers in the future.Based on the above,the application of infrared hyperspectral imaging in long distance gas detection is overviewed,and its unique advantages are also analysed.Finally,the development direction of infrared hyperspectral remote sensing imaging is depicted.
