Abstract

According to data obtained at atmospheric path, was tested an algorithm for calculating the transverse component of the wind speed by correlation analysis of measurements on the Shack-Hartmann wavefront sensor. The correlation method is based on the hypothesis of "frozen" turbulence. Calculated correlation values are the coefficients of the linear correlation between the displacements of the coordinates of the centroids. To automate the algorithm for calculating the transverse component of the wind speed were created the following programming techniques: the moving average method, the gradient descent method, the method of calculation of derivatives.
