Abstract

Structure Function is under investigation to better specify the atmosphere turbulence, which is represented by r0. Its fast calculation algorithm, taking advantage of Fast Fourier Transfer and Power Spectral Density, is presented in this work. The Zernike polynomials in frequency domain were used to release the error characteristics of this algorithm, which also determines the number of averaging. Lastly, the structure function and air correlation length are reached by the algorithm presented here.
