We propose to use multiphoton interferences of photons emitted from statistically independent thermal light sources in combination with linear optical detection techniques to reconstruct, i.e., image, arbitrary source geometries in one dimension with subclassical resolution. The scheme is an extension of earlier work [S. Oppel et al., Phys. Rev. Lett. 109, 233603 (2012)], where N regularly spaced sources in one dimension were imaged by use of the Nth-order intensity correlation function. Here, we generalize the scheme to reconstruct any number of independent thermal light sources at arbitrary separations in one dimension, exploiting intensity correlation functions of order m≥3. We present experimental results confirming the imaging protocol and provide a rigorous mathematical proof for the obtained subclassical resolution.
我们提议将统计独立热光源发射的光子的多光子干涉与线性光学检测技术相结合，以在一维中以亚经典分辨率重建（即成像）任意源几何结构。该方案是早期工作 [S. Oppel 等人，《物理评论快报》109, 233603 (2012)] 的扩展，在早期工作中，一维中 N 个等间距的源通过使用第 N 阶强度关联函数进行成像。在此，我们将该方案推广到在一维中重建任意数量、任意间距的独立热光源，利用 m≥3 阶的强度关联函数。我们展示了证实成像协议的实验结果，并为获得的亚经典分辨率提供了严格的数学证明。
