In computational holography, the realization of multi-plane holographic display based on layer-based method is one of the most commonly used methods. Aiming at the problem of crosstalk between multiple planes in layer-based method, this paper combines the advantages of random phase and quadratic phase, and proposes a multiplanar holographic display method based on hybrid phase. First, a suitable weighting factor is selected to generate the hybrid phase instead of the random phase as the initial phase. After iteration using the iterative Fourier transform algorithm, each obtained sub-hologram is superimposed with Fresnel zone plate with different reconstruction distances. Then, each hologram is superimposed with complex amplitude, and a phase-only hologram is obtained after the phase is obtained, thus the layered image is reconstructed on the specified plane. A multi-plane holographic display system is constructed using a liquid crystal on silicon to carry out relevant optical experiments. The experimental results show that the structural similarity parameter of this method is improved (up to 4.6%) compared with the random phase-based method, which attenuates the crosstalk between multiple holographic reconstruction planes and improves the reproduction quality of the multi-plane holographic display.
