Abstract
The standard FFT, optical propagation computer code-applicable method for calculating realizations of phase screens to simulate the effects of atmospheric turbulence is presently modified to include such LF aberrations as tilt. It is shown that the modified phase screens yield superior statistical representations of Kolmogorov turbulence, and comparisons of simulations employing such modified phase screens with the results of theoretical calculations for Strehl ratio with finite outer-scale effects are presented. The modified method is noted to be highly memory-efficient, relative to the phase screens used for the propagation simulations.
