Possibilities of 2D velocity field visualization in the atmosphere with the help of the laser radiation scattered by particles, which move in a turbulent air flow, have been analyzed. With the aid of numerical simulation, it is demonstrated that the visualization of the flow velocity field is possible based on displacements of large-scale intensity inhomogeneities in the speckle structure, arising in the optical image of the scattering layer region illuminated by a laser.
