High-Definition Image CGH Created by Polygon-Based Method and its Reconstruction by White Light

Abstract

Image-type binary CGHs commonly lost the surface shading and texture-mapping in the optical reconstruction. This is caused by the binary amplitude fringe that is unable to reconstruct object brightness because amplitude information of the object field is removed by binarization if the object is close to the hologram. In this paper, an optimized error diffusion technique is proposed to improve shading and texture-mapping. Image-type high-definition CGHs created by the proposed technique can be reconstructed by white light.
