Abstract

Experimental observations of the coherence enhancement phenomenon are presented and described. We have illuminated an optically rough moving target through turbulence using two mutually coherent point sources and observed the interference of the scattered fields in the region close to the sources (the region of coherence enhancement) with the help of a special interferometric system. The experiment was carried out under weak and strong intensity fluctuations on the object. Our study shows that the intensity distribution in the region of coherence enhancement is determined by the four-point correlation function and depends on the inner scale of the turbulence.
