摘　　要：利用光子晶体的概念和方法 ,从理论上分析了一维全息图在再现光以不同角度入射情况下禁带结构的性质。分析表明 ,当再现光非正入射时 ,体积全息图的禁带结构是倾斜的 ,正入射时的非倾斜结构是倾斜结构的一个特例。Based on the concept and the treating techniques for photonic crystals, the characteristics of the forbidden band structures in one dimensional reflection hologram are analyzed. It is treated in the consideration of the reconstruction beam being incident to reflection hologram at different incident angles. The analysis shows that, for oblique incidence, the structures of forbidden band in hologram are slanted. For normal incidence, the structures of forbidden band in hologram are unslanted, and it is the special case of oblique incidence.
