在遥感领域,高光谱成像技术于20世纪末取得了重大突破,它是当前遥感领域的前沿技术之一。干涉成像光谱仪是继色散成像光谱仪之后新出现的一种成像光谱仪,它通过获取目标干涉图,从而间接得到高光谱影像的先进遥感设备,具有高通量、多通道以及光谱采样连续等诸多优点,代表着未来高光谱发展的一个重要方向。结合西安光机所在干涉成像光谱方面的科研工作,比较了干涉成像光谱仪与色散成像光谱仪的优缺点,分析了干涉成像光谱仪的工作原理,结合项目进行的机载飞行试验结果,介绍了干涉成像光谱仪在目标识别、农作物普查等方面的应用。
In the field of remote sensing, hyperspectral imaging technology made a major breakthrough at the end of the 20th century. It is one of the leading technologies in the field of remote sensing. Interferometric imaging spectrometer is an emerging imaging spectrometer after the dispersive imaging spectrometer. It obtains the advanced interferometric device of hyperspectral image directly by acquiring the target interferogram, and has the advantages of high throughput, multi-channel and continuous spectral sampling, Represents an important direction for the future development of hyperspectral. The advantages and disadvantages of interference imaging spectrometer and dispersive imaging spectrometer are compared with the research works of the Xi’an Photomechanical Interference Imaging Spectrometer. The working principle of the interference imaging spectrometer is analyzed. Based on the flight test results of the project, the interference imaging spectrometer In the target identification, crop census applications.
