Multi-plane holographic display algorithm based on hybrid phase
摘要
Abstract
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.关键词
