By exploiting polarization correlations of light from a broadband fiber-based amplified spontaneous emission source we succeed in reconstructing a hidden polarization in a ghost polarimetry experiment in close analogy to ghost imaging and ghost spectroscopy. Thereby, an original linear polarization state in the object arm of a Mach-Zehnder interferometer configuration which has been camouflaged by a subsequent depolarizer is recovered by correlating it with light from a reference beam. The variation of a linear polarizer placed inside the reference beam results in a Malus law type second-order intensity correlation with high contrast, thus measuring a ghost polarigram.
通过利用基于宽带光纤的放大自发辐射源发出的光的偏振相关性，我们成功地在鬼偏振测量实验中重建了隐藏的偏振，这与鬼成像和鬼光谱极为相似。由此，马赫-曾德尔干涉仪配置的物臂中原本被后续去偏振器伪装的线性偏振态，通过将其与参考光束的光进行关联得以恢复。放置在参考光束内的线性偏振器的变化会导致具有高对比度的马吕斯定律型二阶强度关联，从而测量出鬼偏振图。
