摘要

利用次谐波方法和Zernike多项式对基于Kolmogorov和Von Karman谱模型的傅里叶变换方法产生的相位屏进行补偿。然后对这两种补偿方法的性能进行了比较。结果表明，在Kolmogorov谱模型中，Zernike多项式具有较好的补偿效果，而在Von Karman谱模型中，次谐波方法能够更精确地补偿相位屏。

Performance comparison of subharnomic and Zernike polynomials method for compensation of low-frequency components in FFT-based Von Karman phase screen

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.
