Abstract

Calculation of the transverse components of the wind speed at the entrance aperture adaptive optical system is based on the correlation analysis of coordinates of energy centers of gravity of the focal spot, that it was measured by wave front sensor Shack–Hartmann. To ensure the accuracy of the algorithm implementing the calculation of wind speed, it must be resistant to noise caused by the construction of sensor and resulting from mathematical operations. It is presented the results of numerical studies. The analysis is performed on basis of a numerical model of the wave front sensor Shack- Hartmann and on turbulence model of Kolmogorov’s type.
