Paper Abstract

In order to design adaptive optics systems and to study the effect of atmospheric turbulence on astronomical images it is helpful to know the temporal power spectra of the various Zernike polynomial terms. These coefficients correspond directly to standard aberration terminology like tilt, astigmatism, spherical aberration and so on. An analytical method based on work by Roddier et al. for predicting these power spectra using the current average wind speed, Frieds parameter r(Omicron ) and the aperture size is presented along with some experimental results testing their predictive power. The data are also shown to confirm the important results of Fried as well as Noll.
