Scientific paper

The possibility is shown that the phase of an object transform can be determined from the autocorrelation of the image transform. The two together should give a diffraction-limited image of the object. A thereon based technique for the recovery of images from atmospherically degraded short-exposure photographs is proposed. Results from a one-dimensional computer simulation are used for a preliminary demonstration of the technique.
