磁全息图中的再现效应可以很容易地解释，如果假设一个线性偏振的平面波读出光束。透过全息图或从全息图反射的场通过法拉第或克尔效应旋转。通过将出现的场分解为两个正交分量，可以为每个偏振定义单独的传输函数。衍射场和磁光栅的效率很容易从这些传输函数计算。对于二元磁光栅，除了零级之外，所有衍射级都与入射偏振正交地偏振。对于正弦磁光栅，各种衍射级在偏振方面交替，其中零级在与入射偏振相同的方向上偏振。
Reconstruction effects in a magnetic hologram can easily be interpreted if one assumes a linearly polarized plane wave readout beam. The field transmitted through or reflected off the hologram is rotated via the Faraday or Kerr effect. By decomposing the emerging field into two orthogonal components, one can define separate transmission functions for each polarization. The diffracted field and the efficiency of the magnetic grating are readily computed from these transmission functions. For a binary magnetic grating all diffraction orders, with the exception of zeroth order, are polarized orthogonally to the incoming polarization. For a sinusoidal magnetic grating, the various diffraction orders alternate in polarization with the zeroth order polarized in the same direction as the incoming polarization.
