High-resolution Fresnel hologram information simplification and color 3D display

摘要

High-resolution color Fresnel hologram is computation extensive. In this research, we propose a spatial sampling method to reduce the information redundancy of high-resolution Fresnel ho-lograms. The color Fresnel hologram by combining of three monochromatic sampled holograms is achieved without barrier effect. Theoretical analysis of human visual perception of the color Fresnel hologram is conducted. A color holographic 3D display method using RGB LEDs as il-lumination sources is implemented for color holographic 3D display using color Fresnel holo-grams with the size of 30 mm x 30 mm at the resolution of 94,208 x 94,208 pixels. The proposed method is verified through experimental study illustrating the effectiveness of the proposed method.
