摘　　要：在对反射式全息图衍射率理论分析的基础上推导了直接影响衍射率的几个物理量与衍射率的 关系式,并根据此式运用MATLAB进行仿真,研究了在不同条件下衍射率的变化趋势.结果表明,此方法是 可行的,且为全息图衍射率的分析提供了一个新途径.Based on the analysis of diffraction efficiency theory of reflection holograms, this paper deduces the formulate concerning the relationship between the several physical parameter that will directly affect the diffraction efficiency. Moreover, in the framework of this formulate, the paper carries out a emulate research of the variation trend of the diffraction efficiency in various conditions based on MATLAB. The results show that this approach is feasible and can offer a new way to study the diffraction efficiency of reflection holograms.
