Abstract

A tempo-spatially mixed modulation Fourier transform imaging spectropolarimeter based on polarization modulation array (PMAFTISP) without internal moving parts was presented, which can obtain the image, spectrum, and full-stokes parameters of the target at the same time. The principle and feasibility were validated with simulations. The system was simulated and the influence of retarder error on the recovery of the full-Stokes parameters was mainly analyzed. Compared with channeled interference imaging spectropolarimetry (CIISP), the system separated four fringe patterns in space, without channel crosstalk as well as simplifying the data processing. Additionally, the advantages of the Fourier transform spectrometer are maintained, such as high throughput (Jacquinot) and multiplex (Fellgett) advantages.
