For completeness, we note that the pixel size of ∼0.3 cm–0.4 cm introduces an inner scale of turbulence into the simulations. This is an unavoidable consequence of all finite element numerical simulations.

In principle, a telescope of any diameter may be simulated. However, for larger-aperture telescopes to be considered, the phase-screen length must also become larger, which in turn requires a larger number of pixels to span the screen’s length. (As discussed in Appendix A, the pixel size is bounded by considerations related to the strength of turbulence and the interscreen spacing.) The computational requirements for dealing with phase screens that have large numbers of pixels can quickly become prohibitive.
