Recovery of blurred images obtained through turbulent media.
Method for recovering blurred images taken through turbulent media, such as the atmosphere is presented. In this method amplitude and phase of the object's image are separately determined by special techniques of data processing, and finally the original image can be recovered. Principle and algorithm are described and the techniques to determine amplitude and phase are introduced by use of the results of computer simulations as well as light propagation experiments. As a demonstration to verify the utility of this method, images recovered by this method by use of data taken through a telescope of 1.5 m diameter, and the results of a computer simulation with atmospheric turbulence are shown. The results suggest that the presented method is well suited for the retrieval of blurred images.
