Reduction in the reconstruction error of computer-generated holograms in liquid crystal panels

摘要

In this paper the research of the real-time three-dimensional holographic imaging system which uses liquid crystal panels to display the computer generated Fresnel holograms for reconstructed 3D images is described. The reconstructed effects are related to each step of the process and the characteristics of the devices. The contradictions between the quantization of holographic numerical data and the properties of the display device are the important reasons for the reconstruction errors. A new algorithm for calculating point holograms is proposed for reducing the reconstruction errors. Finally the original experimental result is given.
