A novel model for obtaining interferogram and spectrum based on the temporarily and spatially mixed modulated polarization interference imaging spectrometer

Based on the temporarily and spatially mixed modulated polarization interference imaging spectrometer (TSMPIIS) developed by us, a novel model for obtaining interferogram and spectrum is proposed. The interference data arrays acquired with this model are analyzed, and the method for combining a series of interferograms at different moments is illuminated in detail. Furthermore, the interferograms of monochromatic light and polychromatic light obtained by TSMPIIS are processed. The satisfying interferogram and reconstructed spectrums show the superiority of this detection model, such as wide field of view, high detection sensitivity and high throughput, etc.
