Phase-retrieval stagnation problems and solutions
James R. Fienup,C. C. Wackerman +1 more
TL;DR: The iterative Fourier-transform algorithm has been demonstrated to be a practical method for reconstructing an object from the modulus of its Fourier transform (i.e., solving the problem of recovering phase from a single intensity measurement).
Wave-front phase estimation from Fourier intensity measurements
TL;DR: In this paper, a wavefront sensor that estimates phase from Fourier intensity measurements is described, and an explicit expression is found and numerically evaluated for the Cramer-Rao lower bound on integrated rms wave-front phase estimation error.

Use of Fourier domain real-plane zeros to overcome a phase retrieval stagnation
C. C. Wackerman,Andrew E. Yagle +1 more
TL;DR: A new procedure that uses only a single image is developed that estimates the locations of real-plane zeros from either the measured Fourier modulus data or a stagnated reconstruction and uses this information in the iterative Fourier transform algorithm to force the complex-valued Fourier data to have real- plane zeros at the correct locations.

Phase retrieval and estimation with use of real-plane zeros
C. C. Wackerman,Andrew E. Yagle +1 more
TL;DR: In this article, a phase retrieval algorithm that uses real-plane zero locations to generate a simple parameterization of the Fourier phase and uses knowledge about the image to estimate the phase parameters is presented.

Contrast ratios of internal waves in synthetic aperture radar imagery: A comparison of SAR Internal Wave Signature Experiment observations with theory
TL;DR: In this article, a theoretical model was developed to extract radar scattering coefficient (σ0) signatures associated with the internal wave patterns observed in the SAR Internal Wave Signature Experiment (SARSEX) data set.
