Abstract

The feasibility is estimated of an approach for measuring the atmospheric wind velocity by spatial filtration of moving turbulence-induced cross-section speckle structure of a propagating laser beam. It is shown that there are some optimum relations between the atmospheric conditions (turbulence intensity, transversal wind velocity) and the experimental arrangement parameters (characteristics of the laser beam, receiving optical system, spatial filter, beam propagation distance etc.), that ensure a maximum measuring sensitivity.
