Abstract

We show that the filtered white noise process applied to logarithmically sampled turbulence spectra executed in cylindrical spatial frequency coordinates produces accurate phase screens that are free of the shortcomings associated with uniform sampling schemes. Decoupled from the sampling requirements of the wave-optics computational mesh in which they are used, the screens have isotropic statistics, do not require low spatial frequency augmentation, have prescribed resolution with more optimum sampling for the simulation, and feature an economical method of achieving screen motion that minimizes memory requirements.
