Problems solved by technology

The device and method need to obtain four sets of polarization interference information under different optical path differences at the target point through push-broom, and then obtain spectral information and full polarization parameters of each spectral segment after spectral restoration and polarization information reconstruction in the later stage. Registration processing, this method is complex and has poor real-time performance, which cannot meet the actual engineering application
