Scattering of coherent light by spatially inhomogeneous disordered media and rough surfaces leads to the formation of stochastic spatial distributions of the scattered light intensity, or speckle patterns. ese patterns have a specic granular structure that results from the random interference of a great number of partial waves scattered by bulk or surface inhomogeneities (see Figure 19.1). e stochastic nature of scattering systems causes random phase shis between these waves and results in statistical properties of the amplitude, phase, and intensity of speckle-modulated scattered elds.
