a Schematic of the procedure for generating a desired CVB-encoded hologram, together with generated the holographic image. The sampling distance of the dot matrix is d = 3 µm. FT: Fourier transform. b Schematic of the CVB-selective holography using a metasurface encoded hologram, along with the design of its basic metamolecule with demultiplexed topological charges of m = ±2, ±3. c Microscopy and SEM images of the fabricated sample. d Experimentally tested results of the CVB demultiplexed holography with topological charges of m = ±2, ±3, and also the even and odd parities. The white-arrows pattern in each subgraph indicates the polarization distributions of the corresponding CVB.
