Abstract
The results of an experimental method for estimating the integral along a wind velocity path, based on the determination of the variance of speed of the energy centroid displacements in the images of a laser beam passed through the path, are presented. The method is compared with optical methods of estimating the integral velocity, based on “temporal” and “spatial” variants of the correlation and spectral analysis of intensity fluctuations in the laser beam images. It is shown by the use of ten sonic anemometers placed along the sounding path that the results of the integral wind velocity estimation by all three optical methods are in agreement with each other and with the results of local measurements of wind velocity.
