We combine Mueller matrix polarimetry (MMP) with spatial frequency domain imaging (SFDI) to create a technique that is sensitive to near-surface material anisotropy. We demonstrate this imaging modality with scattering and absorbing phantoms and with a fiber optic bundle. Images of depolarization show reduced depolarization under high spatial frequency illumination and demodulation and in some cases, reduced contrast to deeper features. The images of a fiber optic bundle show marked differences between illumination modulations that are aligned with the fibers versus those crossed with the fibers, demonstrating the impact of polarization on scattering direction.
