Abstract

We discuss the nature and general properties of the effect with regard to the imaging through the turbulent atmosphere. This new effect utilizes the medium inhomogeneities as a part of the optical system to obtain the resolution beyond the diffraction limit. Turbulence superresolution effect relates to the focusing properties of the random medium. We discuss some general properties of image distortions by random refractive medium and present the experimental results revealing important statistical connections between global properties of distorted image and superresolution events. We present the results of the postdetection processing of the short- exposure images which is capable to preserve and accumulate information beyond the diffraction limit.
