Abstract

The present paper considers the results of experimental testing for the optical method of determination of the transversal mean wind velocity and its variance is discussed. This method is based on the measurements of velocity variance of an illuminance centroid displacement in the focal plane of receiving lens. The obtained wind velocity values are compared with synchronous values of independent optical method, which is based on measurement of cross-correlation of intensity fluctuations in two points in receiver planes. Reasonable agreement of wind velocity values obtained in two methods as well as data of an acoustic anemometer placed on a sensing path at moment of measurements is shown.
