Abstract

Atmospheric turbulence may significantly degrade the image of an object below the diffraction limit of the imaging system's aperture. A probabilistic method for overcoming this image degradation has been proposed by Hufnagel and Fried.¹ It consists of making short exposure images of the object. At some instants the wave front distortion upon the receiving aperture may be negligible. If a short- exposure (<5-msec) image is made, it will appear to be diffraction-limited.
