    Abstract

    Because of the low imaging resolution of holographic stereogram, a method using wavefront plane is proposed to improve imaging quality. The resolution limit of holographic stereogram is mainly affected by spatial sampling, angular sampling and diffraction. The influences due to these factors are analyzed with mathematical equations. Supposing that the distance between hologram and human eyes is about 600 mm, the relationship between imaging resolution limit and depth of three-dimensional scene or Hogel size is provided according to acuity of human eyes. The depth limit of three-dimensional scene and optimal Hogel size are 12.80 mm and 90 μm, respectively, if the wavelength is 632.8 nm. A wavefront plane which is decided by depth limit is set. The experiments are performed with two three-dimensional scenes to evaluate the proposed method. With numerical simulation method, the tank model which has complicate structures is reproduced. The elaborate features of tank model at every depth are accurately obtained. A teapot model is optically reconstructed with holographic three-dimensional display system based on spatial light modulator. The three-dimensional cues such as depth and gloss are well provided in the reconstructed images.
