    "abstract": "We demonstrate experimentally a novel technique for characterizing transverse\nspatial coherence using the Wigner distribution function. The presented method\nis based on measuring interference between a pair of rotated and displaced\nreplicas of the input beam with an area-integrating detector, and it can be\nsuperior in regimes when array detectors are not available. We analyze the\nquantum optical picture of the presented measurement for single-photon signals\nand discuss possible applications in quantum information processing.",
