Inter-layer edge artifact-suppressed multi-plane target amplitude synthesis for phase-only hologram generation

Computer-generated holography for three-dimensional (3D) display has the potential to provide correct depth cues and realistic occlusion relationships. However, existing multi-layer image-based methods tend to suffer from crosstalk and ringing artifacts at inter-layer edges in complex scenes, which significantly degrades the reconstruction quality. To address this issue, we propose an inter-layer edge artifact-suppressed multi-plane target amplitude-driven phase-only hologram generation method. The proposed method requires only a single RGB image as input. First, a set of multi-plane target amplitude distributions with suppressed edge artifacts and physically plausible depth-of-field effects is synthesized. Then, a single phase-only hologram is iteratively optimized under multi-plane amplitude constraints. Experimental results demonstrate that the proposed approach more effectively suppresses inter-layer ringing and crosstalk in complex 3D scenes, yields more continuous depth perception, and enables high-quality phase-only holographic reconstruction.
