Paper Abstract
Simulation of the dynamic effects of atmospheric turbulence assists in understanding, testing and effective implementation
of adaptive optics systems. Statistical interpolation technique helps in retaining the spatial turbulence
statistics when atmospheric phase screens are required to be moved by non-integer multiples of the grid spacing.
We applied statistical interpolation in the simulation of temporally evolving phase screens using the multilayer
model of atmospheric turbulence. A comparison of the statistical method with bilinear interpolator and random
midpoint displacement method is presented. It is shown that underestimating Fried's parameter (r0) in the
interpolation leads to large errors and hence it is appropriate to choose a little larger value of r0 than estimated
from the phase screens.
