本文报道了用双光子相关测量所观察到的异常衍射和干涉现象。自发参量下转换产生的信号和闲散光束沿不同方向发送，并由两个相距较远的点光子计数探测器检测。在信号波束中插入双狭缝或单狭缝。在怠速光束中扫描探测器，观察到干涉-衍射图案。
Observations of unusual diffraction and interference by two-photon correlation measurements are reported. The signal and idler beams produced by spontaneous parametric down-conversion are sent in different directions, and detected by two distant pointlike photon counting detectors. A double slit or a single slit is inserted into the signal beam. Interference-diffraction patterns are observed in coincidences by scanning the detector in the idler beam.
