Abstract
It has been shown that the knowledge of intensity distributions?f(x)?2 and |(df(x))/dx| 2 in the image plane, where f(x) is the complex amplitude distribution, suffices to determine uniquely the respective phase distribution. The recovery is then reduced to determining the cut-off frequency and stating whether the intensity coming from the spatial frequency spectrum at a point coordinate equal to the right-hand cut-off frequency is greater (or less) than the intensity at the point of coordinates equal to the left-hand cut-off frequency
