Abstract
The theoretical model for studying the self-healing of the spatial coherence of a light beam is constructed. Based on this model, the evolution of the degree of coherence for a partially coherent Gaussian Schell-model beam is studied in detail. This study shows the existence of the self-healing effect of the partial coherence for this beam. The self-healing process is determined by the disturbing strength of the turbid medium, the beam width, and the initial coherence. An example of the application of the self-healing property is provided in the case of ghost imaging, if the initial beam is blurred by certain turbid media.
