Polarization-multiplexed metasurface holography. a The concept of diatomic metasurface based on detour phase principle for achieving vectorial holography [28]. b Design principle of the multi-freedom metasurfaces for completely controlling the amplitude, phase and polarization of output light simultaneously. The simulated and experimental results of reconstructed full-color images for different combinations of polarization orientations are shown on the bottom [29]. c Simulated and experimental results for the reconstruction of a dice with different exposed faces by using different combinations of input/output polarization [73]. d Schematic of a metasurface projecting a desired polarization pattern with arbitrarily complexity. Simulated and measured polarization holograms after converted to false-color images are shown on the right panel [74]
