Abstract

We present a novel spectro-polarimetric long-wave infrared (LWIR) thermal imaging system based on spinning metasurfaces. By utilizing the intrinsic dispersion in high-contrast anisotropic metasurfaces, we are able to generate tunable transmission spectra and achieve high spectral resolution. Our system enables simultaneous spectrum- and polarization-resolved thermal imaging, allowing for the extraction of hidden information in thermal radiation. Our low size, weight, and power (SWaP) system is a promising next-generation solution for high-quality thermal imagery data.
