Imaging setup (IMAGE) Optica Caption The stack of spinning metasurfaces breaks down thermal light into its spectral and polarimetric components. The researchers combined the metasurface stack with a traditional long-wave infrared camera and computational imaging algorithms to create a compact and robust spectral thermal imaging system.
