面向空间光调制器的三维全息编码方法

In this paper, the three-dimensional holographic coding methods facing the spatial light modulator (SLM) holographic coding methods have been investigated. Using Digital Micromirror as SLM and utilizing the volume slice approach, relationships between imaging distances and foci of convergent lenses have been analyzed. On the basis of imaging distance, SLM’s physical microstructure and Fresnel diffracting condition, the holographic sampling, calculating and coding methods have been designed. It’s proved that the hologram coded could reconstruct several slice images in different spatial positions. The research in this article would be used as reference to the theory, arithmetic and system implement of three-dimensional holographic code.
