Abstract
We compensate the phase screens generated by the Fourier Transform method based on Kolmogorov and Von Karman spectrum models with subharmonic method and Zernike polynomials. Then we present the performance comparison of these two compensation methods. The results show that in Kolmogorov spectrum model, Zernike polynomials have better compensation effect but in Von Karman spectrum model, subharmonic method can compensate the phase screens more accurately.
