We present the experimental characterization of two distant double-slit masks illuminated by chaotic light, in the absence of first-order imaging and interference. The scheme exploits second-order interference of light propagating through two indistinguishable pairs of disjoint optical paths passing through the masks of interest. The proposed technique leads to a deeper understanding of biphoton interference and coherence, and opens the way to the development of novel schemes for retrieving information on the relative position and the spatial structure of distant objects, which is of interest in remote sensing, biomedical imaging, as well as monitoring of laser ablation, when first-order imaging and interference are not feasible.
我们展示了两个远距离双狭缝掩模在无一级成像和干涉的情况下被混沌光照明的实验特性。该方案利用通过经过感兴趣的掩模的两对不相交的光学路径传播的光的二阶干涉。所提出的技术导致对双光子干涉和相干性的更深入理解，并为开发用于检索关于远距离物体的相对位置和空间结构的信息的新方案开辟了道路，这在遥感、生物医学成像以及激光烧蚀监测中是感兴趣的，当一级成像和干涉不可行时。
