当光源-狭缝距离使得入射光束相干区的所有维度都小于狭缝之间的距离时，有可能检测到来自具有杨氏狭缝的扩展非相干源的干涉吗？实验证明，在上述条件下，通过下转换发光的共轭光束之间的符合测量，可以获得可见度可控的干涉条纹。
Is it possible to detect the interference from an extended incoherent source with Young's slits when the source-slits distance is such that all dimensions of the coherence area of the incident light beam are smaller than the distance between the slits? We have experimentally demonstrated that, under the above conditions, interference fringes can be obtained with a controlled degree of visibility by means of coincidence measurements between conjugated beams of the down-conversion luminescence.
