英文摘要： The spectrum and polarization which are often used to identify the target are important radiation characteristics of the target. The detection technology that fuses spectral and polarization information and owns the advantages of both significantly improves the ability to effectively indentify the target in a complex background. It plays an important role in the field of military reconnaissance, disaster estimation and resource exploration. Around the problem of detecting the target spectra and polarization information, we are committed to research a fusing imaging method to detect hyperspectral and all Stokes polarization information. We detect all Stokes polarization information with the principle of light field imaging on the basis of the image plane interference imaging spectrometer. We get the pushbroom interference signals and recover the spectral information of the targets which have different spectral width by using the method of compressive samplingin order to improving the detection efficiency. As the same time, we research the high precision spectrum recovery method and super-resolution recovery method so as to find a good detection technology that can be used to get multi-scale spectrum and full polarization of targets. This project is the further research of hyperspectral imaging detection and spect
