2 it can be seen that linear and quadratic aberrations are affected considerably by the loss of spatial scales larger than the size of the computational grid. This fact is also confirmed by calculation of the variance for the coefficients of wavefront expansion in terms of the Zernike polynomials for turbulent spectral density with the finite outer scale. The parameter 1 , which characterizes phase distortions minus the phase constant over the entire aperture (polynomial Z1 ), is much less than the corresponding theoretical value.
