With the development of micro/nano fabrication technology,metasurface holography has emerged as a revolutionary technology for the manipulation of light with excellent performance.However,for applications of full-Stokes polarization encryption and time sequence holographic display,multiplexing strategies of metasur-faces with large bandwidths and simple operations still need to be developed.As one of the most popular schemes of multiplexing,polarization multiplexed metasurfaces have shown flexible recording abilities for both free-space beam and surface waves.Here,by using a dielectric metasurface equipped with double phase holograms,we have achieved flexible polarization multiplexed transformations from one full-Stokes space to another.The vectorial hologram is optimized by a hybrid genetic algorithm and digitalized with subwavelength modulated units.Based on a quanti-tative map and remarkable information capacity,time sequence holographic display and complex optical encryption are experimentally demonstrated by changing input/output polarization channels in real time.We believe our method will facilitate applications in smart compact devices of dynamic display,dynamic optical manipulation,optical encryption,anticounterfeiting,etc.
