Paper Abstract

We show that the Gerchberg-Saxton iterative phase recovery algorithm can generate usefully accurate image phase distributions, when the magnitude of the image's Fourier transform is given (or measured) very accurately but only a moderately accurate version of the image magnitude is available. The performance of our modified Gerchberg-Saxton algorithm is illustrated with two examples for which the data were computer-generated: the first, being one-dimensional, is relevant to acoustic microscopy, while the second relates to deducing, from the magnitude of its radiation pattern, the forms of the imperfections in the two-dimensional aperture distribution of a radio antenna.
