Statistics of the phase and intensity of speckles formed with a small number of scattering events (small-N speckles) within multiple-scattering media have been studied. It has been demonstrated that first-order statistics of the intensity fluctuations of small-N speckles nearly obey a Nakagami n distribution in the case considered. The correlation function of the complex amplitude of scattered light is close to a negative exponent. Theoretical results have been experimentally verified using the Shack–Hartmann wavefront analysis technique.
