摘　　要：In light of the powerful light manipulation ability of holographic metasurfaces,optical imaging with wavelength multiplexing and polarization multiplexing is performed in this paper.The metasurface is composed of identical rectangular nanoholes etched in silver film.Three imaging effects,including the in-plane color imaging,three-dimensional wavelength-encrypted imaging,and polarization-multiplexing wavelength-encrypted imaging,are realized.The designed metasurface has compact structure,and the obtained image has lower noise.The simulation and experiment results give the verification.Multiple images,including spatial multiplexing,wavelength multiplexing,and polarization multiplexing,exhibit immense potentialities of metasurfaces,and this work is helpful for expanding the applications of metasurfaces.
