Comparison between conventional spectropolarimetry and computational spectropolarimetry based on a tunable metasurface. a,b Schematics of conventional division-of-amplitude (a) and -time (b) polarimetry and spectrometry. c Schematics of computational spectropolarimetry with a tunable liquid crystal metasurface. Light with unknown polarization and spectrum normally impinges on the liquid crystal metasurface. Both the polarization and spectrum of the incident light can be computationally reconstructed from the measured intensity of the reflected light
