We proposed a multi-modulated HDS solution employing the amplitude, phase and polarization at once. Based on principle of polarized holography, 2-channel polarized multiplexing can be realized. Combined with deep learning, a lensless near field diffraction intensity model can be used to demodulate four-level amplitude and four-level phase at the same time. Compared with traditional HDS, the multi-modulated HDS can increase the storage density by about 10 times.
