摘要	A numerical simulator of a turbulence phase screen based on turbulence power spectrum density is described in this paper. The low-frequency adding technique used in the fast-Fourier-transform-based method is extended to the whole frequency domain. The frequency range and spatial coordinates are no longer limited by the spatial sampling, so that the phase screens can be applied in the multi-beam time-dependent scenario. Several spectrums can be applied in this simulator. The structure function, modulation transfer function, and variance of the Zernike coefficient are calculated with the Kolmogorov model for validation. The simulation results have shown good agreement with the theoretical results.; A numerical simulator of a turbulence phase screen based on turbulence power spectrum density is described in this paper.
