摘　　要：报道了正交线偏光全息中的正交再现现象。所谓的正交再现,指的是衍射光的偏振态与记录信号光的偏振态是正交的。基于新发展的张量偏光全息理论,分析了正交再现的条件;搭建实验平台,在实验上观察到正交再现现象。通过定量分析与多组实验,可以得出当衍射光实现正交再现时,其功率大小与记录过程中信号光和参考光的干涉夹角有关。实验结果和理论分析结果完全吻合。正交再现现象的发现,有望拓展对偏光全息理论的认知。In this paper,we investigate the orthogonal reconstruction in orthogonal linear polarization holography.Orthogonal reproduction means that the polarization of the diffracted light is orthogonal to the polarization of the recorded signal light.Based on the newly developed polarization holography theory with the tensor method,we analyzed the prerequisite for orthogonal reconstruction and verified it experimentally by constructing an experimental platform.Through quantitative analysis and multiple experiments,the power of the diffracted light was related to the interference angle between the recorded signal light and reference light during the recording process when the diffracted light was subjected to orthogonal reconstruction.The experimental results are in good agreement with the results obtained via theoretical analysis.Thus,our knowledge related to polarization holography may be improved through orthogonal reconstruction.
