Novel snapshot type polarization spectral imaging system with adjustable multi-dimensional parameters

The invention discloses a novel snapshot type polarization spectral imaging system with adjustable multi-dimensional parameters. The system is composed of an objective lens, a collimating mirror, a light splitting grating, a convergent mirror A, a digital micromirror device (DMD), a convergent mirror B, a light combining grating, a sub-aperture polarization assembly, a charge coupled device (CCD) and a computer. The polarization spectrum system controls the reflection direction of a code element corresponding to a coding matrix to carry out spectrum resolution modulation based on a programmable function of the DMD, carries out polarization state modulation of measured light through a sub-aperture polarization assembly, and carries out spatial resolution modulation by adopting a CCD pixel merging method. And finally, flexible modulation of multi-dimensional parameters of the novel snapshot polarization spectrum system is realized. The imaging system has the capability of flexibly modulating the spatial resolut
