The problem of imaging when a region of extended turbulence is present between the object and imaging optics is studied. A simple ray model for the distortion introduced by the turbulence is adopted which leads to a mathematical description of the instantaneous image degradation. two novel methods for retrieving an estimate of the object from data consisting of a number of degraded short exposure images are described.
