Viewing angle enlargement in holographic 3 D display by spatial light modulators tiling in curved configuration
摘要
Abstract
In this paper, we analyzed the principles of tiling SLMs to enlarge the viewing angle of holographic 3D reconstructions.Based on the idea of tiling multi-SLMs, we designed a holographic 3D display system u-sing planar mirrors, beam splitters and two transmission-type SLMs tiled in curved configuration to enlarge the viewing angle of reconstructed image.We calculated computer-generated holograms of a pyramid using slice-based Fresnel diffraction algorithm, and reconstructed it with self-setup holographic display system.The re-sults indicate that, in contrast to 1.7°of viewing angle obtained by a single SLM, the viewing angle of holo-graphic reconstructed images is enlarged to 3.2°with 2 tiling transmission-type SLMs by about 1.9 times.The beam splitter can remove the gap of two SLMs′active areas to realize seamless tiling.This method is also ap-plicable to tile more SLMs in curved configuration and can effectively enlarge the viewing angle of holographic display.关键词
