This study presents a spectroscopic polarimetric imaging system that integrates single-pixel imaging (SPI) with dual-comb spectroscopic polarimetry (DCSP) to enable scan-less birefringence mapping. The proposed system simultaneously acquires amplitude and phase spectra of two orthogonal polarization components using DCSP, while SPI eliminates the need for mechanical scanning by employing structured illumination with a spatial light modulator. Experimental validation using a USAF 1951 birefringent test chart demonstrated successful acquisition of birefringence images corresponding to the fast-axis.
