Optical orbital angular momentum (OAM) holography provides a critical method for holographic information storage systems and experimentally demonstrates the feasibility of holographic multiplexation. Herein, the elliptic perfect optical vortex orbital angular momentum (EPOV-OAM) multiplexed holography is proposed and experimentally implemented. The mode selectivity of the ellipticity and rotation angle are investigated, respectively, which demonstrates that those parameters can be used as additional encoded degrees of freedom for the holographic multiplexing. The combination of the topological charge (TC), scaling factor, rotation angle, ellipticity can provide a four-dimensional multiplexed holography for information encryption. Furthermore, the minimum interval of TC for holographic multiplexing could reach 0.01. The method proposed here can enhance the information capacity and the security level of the holographic optical encryption systems.
