Dynamics of statistically inhomogeneous speckles: a new type of manifestation of the Doppler effect.
The diffraction of a focused Gaussian beam from a moving random phase screen is discussed. The correlation function of intensity fluctuations of statistically inhomogeneous dynamic speckles is studied. A theoretical and experimental analysis of the peculiarities of a new type of manifestation of the Doppler effect for focused Gaussian beam scattering is carried out.
