Abstract

The theory of speckle interferometry shows that the averaged squared modulus of the atmospheric-lens modulation transfer function becomes proportional, for high frequencies, to the lens modulation transfer function. The experimental curve obtained by comparison of the power spectrum of a turbulence-degraded image and that of a nondegraded image of the solar granulation is consistent for high frequencies with the theoretical curve. We propose to use it to correct power spectra obtained with a large ground-based telescope, at frequencies up to the diffraction limit.
