a The design approach for a \({\mathcal{M}}\)-multiplexed hologram. b A multiplexed hologram containing the information of the letters “SJTU''. c Planar wave reconstruction. No discernible information is retrieved under planar wave illumination. d Simulation and experimental reconstruction with the correct operator pathways. e 9-channel \({\mathcal{M}}\)-multiplexed hologram, achieving ninefold capacity enhancement over conventional OAM holography
