本文从理论和实验上研究了一对相互关联的谢尔模型光源产生的光的干涉。由两个源产生的场的空间分布通过它们在源平面中的公共中心相对于彼此反转。当光束同相时，在光束强度空间分布的中心出现亮点。当光束具有相移phi= pi时，在光束强度的空间分布的中心出现暗点。实验结果表明，这些结果包括在内。亮斑和暗斑随着离光源距离的增加而发散的速度比光束本身慢。
We study theoretically and experimentally the interference of light produced by a pair of mutually correlated Schell-model sources. The spatial distributions of the fields produced by the two sources are inverted with respect to each other through their common center in the source plane. When the beams are in phase, a bright spot appears in the center of the spatial distribution of the beam intensity. When the beams have a phase shift phi= pi, a dark spot appears in the center of the spatial distribution of the beam intensity. Experimental results that illustrate these results are included. Both bright and dark spots diverge more slowly with the increasing distance from the sources than the beam itself.
