    The simultaneous acquisition of spatial information,spectral information and polarimetric information canobtain more characteristic information to distinguish targets. Aiming at the problems that traditional spectral polarizationimaging technology requires dynamic modulation,low luminous flux,limited spectral resolution and complicatedcomputation etc.,a new imaging mode based on imaging fiber bundles and pixel-level polarization detector is proposed.Combining the fiber-optic imaging spectroscopy and pixel-level polarization information extraction technology,the twodimensionalspatial information,one-dimensional spectral information and four Stokes polarized information of the targetcan be acquired in a snapshot mode. Combined with the system model,an experimental device is set up to obtain four-anglespectral polarization images of 200 spectral bands ranging from 430 nm to 630 nm(spectral resolution is about 1 nm),aswell as the degree of polarization and polarization angle of each spectral band. The system’s spectral polarization imagingdata acquisition capability,and the correctness and feasibility of the technical principle are verified. The technology hashigh application value in the fields of astronomical observation,atmospheric detection,target recognition and other fields.
