Abstract
The conventional approach to three-dimensional holographic displays involves the iterative generation of holograms, which is time-consuming and results in poor reconstruction quality. This paper proposes a novel non-iterative approach to generate 3D phase holograms using a full support optimized Fresnel random phase (FS-OFRAP) method, which combines the FS-OFRAP method and the idea of 3D object layering. The proposed method involves using the iterative Fresnel method to generate FS-OFRAPs of different planes, followed by the non-iterative generation of holograms corresponding to different layers using the 3D object layering strategy. Finally, the final phase hologram is obtained through superposition or multiplexing. Numerical and optical experiments demonstrate the effectiveness and advantages of the proposed 3D-FS-OFRAP method. This new approach has the potential to significantly improve the efficiency and quality of 3D holographic displays.
