成像光谱仪是一种空间遥感探测器，它可以同时获取目标的空间和光谱分布信息。针对机载区域遥感需要结构简单、价格适中和数据处理迅速的成像光谱仪的特点，在窄带多光谱遥感成像仪基础上，提出了一种具有实时光谱图像处理功能的多光谱成像技术。该技术可在窄带多光谱成像过程中同时完成多光谱图像的并行处理，它大幅度地提高了成像光谱仪遥感图像处理的实时性。更为重要的是该成像技术具有极高的性能价格比优势，可广泛用于农业、地质与环保等领域。

Imaging spectrometer is a kind of space remote sensing detector. It can get space and spectral distribution information of a target at the same time. A technique having real-time spectral perform ance is presented with cons ide ration of simpie construction, low cost and high data processing speed. This technique can be used to process multispectral image parallelly and to obtain remote sensing im age processed directly in the process of narrow band muttispectral imaging. The rear-time performance of remote sensing spectrometer can be largety improved. More importantly, this image processing technique has the excellent performance-to-cost ratio and can be applied in agriculture, geotogy, environmental protection and so on.
