摘要
根据耦合波理论,从描述反射全息的非线性微分方程出发,对反射全息图的振幅反射系数进行了分析.结果表明,在低反射及高反射这2种情况下,反射系数均可表示耦合函数的傅立叶变换.这个结果解析地表明,全息图的再现过程实质上是一个菲涅耳衍射的过程.
According to coupled wave theory, and from the non-linear differential equation describing characteristics of reflection hologram, the reflective coefficient of reflection hologram is analyzed. It shows that under the conditions of low and high reflectivity, the reflective coefficient can be expressed by Fourier transform of the product of coupled function and a phase factor. The result points out analytically that, actually, the reconstructing process of hologram is a process of Fresnel diffraction.
