研究了单色点光源在随机介质中产生的光强分布。强度强度相关函数的计算和它示出的强度，作为坐标的函数，表现出大的波动（散斑图案）。本文还研究了这种散斑图对源频率微小变化的敏感性。
The intensity pattern generated by a monochromatic point source in a random medium is studied. The intensity-intensity correlation function is calculated and it is shown that the intensity, as a function of coordinate, exhibits large fluctuations (the speckle pattern). The sensitivity of this speckle pattern to small changes in the source frequency is also studied.
