用高光谱和偏振图像进行遥感（Hyperspectral and polarimetric imagery are used for remote sensing） Infrared magazine 2003 Hyperspectral and polarimetric imagery are used for remote sensing Introduction Light in the light that is emitted or reflected by an object Spectral components are used for target detection and recognition using hyperspectral imaging techniques Dont be very hopeful. In general, the spectrum in the image becomes A filter or dichroic element with spectral separation function can be used Such as acousto-optic tunable filter (AoTF filter wheel) Radiation gratings and prisms are obtained. In order to rapidly change the field Scene hyperspectral imaging, it is best to choose a flexible, can Programmed filter step components, because the spectral section is chosen with the target in order to Associated with the background. Hyperspectral imaging technology is not yet available One of the main reasons for gaining popularity is the adoption of traditional technology Hyperspectral imaging requires processing large amounts of data. Based on AoTF Technology The imager can give the next generation a compact, lightweight, reduced volume The development of this programmable hyperspectral imaging system brings many Convenience. They can not only solve the problem of data bottleneck, but also Polarization characteristics can be provided to form better target detection Discrimination ability. Natural objects such as soil and vegetation Generally, there are many irregular shapes in many applications, They are often the context in which people are concerned. With this natural substance Compared to objects, the polarization characteristics of man-made targets are easier to distinguish. Hyperspectral imaging systems with spectral and polarization discrimination capabilities will be Significant contributions will be made in the future of various remote sensing applications. The US Army Research Laboratory is developing a compact, Compact, anti vibration, rugged, flexible, and portable
