Polarimetric images can provide information such as shading and surface morphologies by using polarizers that selectively reflect the transverse electric (TE) field and transmit the transverse magnetic (TM) field of unpolarized incident light. However, current IR polarizers are mainly based on expensive and brittle ceramics (such as semiconductors and chalcogenides) with nano-gratings usually fabricated by time- and cost-consuming interference lithography.
