Abstract

Previous study of imaging of a coherently illuminated object through turbulence has shown that the average energy spectrum contains diffraction-limited information of the object. It is generally assumed that the object to be imaged lies within a single isoplanatic patch. In this paper the turbulence-induced anisoplanatism and its effect on the imaging of a coherently illuminated object which is larger than the atmospheric correlation length is discussed. It is shown that the dependence of the wave structure function on the object co-ordinates may lead to the characteristics of superresolution, and the average energy spectrum may contain more information than diffraction-limited information in vacuum.
