Abstract
A method to convert two-dimensional(2D) image into three-dimensional(3D) holography display is proposed. The conjectured phase distribution is directly obtained by a polynomial equation based on the 2D image, and is superimposed over the object plane. The parameters of polynomial equation are automatically calculated by the gray value of 2D image. A special kinoform is designed, which contains the phase information generated by Fresnel diffraction algorithm. It can effectively suppress the speckle noise. The sequential kinoforms are reconstructed by the 3D dynamic holographic display system with phase-only liquid crystal spatial light modulator (LC-SLM) and the cylindrical fog screen. The results of simulation and optic experiment exhibit that the proposed method can reconstruct 3D scenes with a better vision effect. The display results show more advantages, such as high contrast, clear detail and low noise. The method presented in this paper can be applied to high performance 3D dynamic holographic display.
