Atmosphere Potentialities of the Methods of the Posteriory Processing of Incoherently Illuminated Objects through the Turbulent

Abstract

Optical transfer function (OTF) and the integral resolution of the optical system "turbulent atmosphere - telescope" are treated theoretically by different methods of posteriory processing of incoherently illuminated objects observed through the turbulent atmosphere. The following processing methods are examined: the averaged image recording ("very long" averaging times) and short-exposure images ("very short" averaging times), namely, Labeyrie, Knox-Thompson, and triple correlation of image intensity methods. The influence of the finite value of the turbulent atmosphere outer and inner scales on the OTF's under consideration is also estimated.
