Deconvolutions and Power Spectra of Solar Granulation
An accurate estimation of power spectra from 2-D white light images suggests the solving of an ill-posed problem (deconvolution) in order to restore high-frequency spectra components depressed by the optical system of telescope and atmosphere. In this paper we address the question what are the influences of deconvolution methods to the features of restored power spectra. Two kinds of deconvolution techniques have been used in order to make this question clear.
