Interferometric hyperspectral polarization imaging method based on micro-polarization array
The spectrum and polarization which were often used to identify the target were important radiation characteristics of the target. The detection technology that fused spectral and polarization information and owned the advantages of both signific antly improved the ability to effectively identify the target in a complex background. It played an important role in the field of environment monitoring, military reconnaissance and atmosphere analysis. Around the problem of detecting the target spectra and polarization information, a fusing imaging method to detect hyperspectral and Stokes polarization information was researched. The methed detected polarization information with the principle of micro-polarization array modulation on the basis of the Sagnac Fourier transform imaging spectrometer. Then a model of the imaging system was designed while the spectrum recovery method and extraction mode of the polarization information were discussed. A prototype was developed and good experimental results of an actual scene objects were obtained. The research shows that besides high throughput and high spectral resolution, the advantages that four polarized fringe patterns are obtained simultaneously also achieved in this method.
