On the ambiguity of the image reconstruction problem
Yu. M. Bruck,L. G. Sodin +1 more
TL;DR: It is shown that the retrieval ambiguity represents a lesser problem in the two-dimensional case compared to the well-known problem of image reconstruction from its spectrum modulus.
Journal ArticleDOI
Speckle interferometry image reconstruction from the Fourier transform phase.
Yu. M. Bruck,L. G. Sodin +1 more
TL;DR: In this paper, a method for the restoration of speckle images from the average phase of the spectrum is described and investigated in detail, and several algorithms that permit unambiguous object image reconstruction (to within arbitrary symmetric factors) have been developed.
Journal ArticleDOI
An Improved Method for Reconstructing Two- and Multidimensional Images from the Phase of Their Fourier Spectrum
Yu.M. Bruck,L. G. Sodin +1 more
TL;DR: In this article, a method for image restoration from the phase of its spectrum requires the solution of sets of linear equations whose number is equal to that of the image elements, which leads to sets involving about 103 equations or more.
Journal ArticleDOI
A broadband hybrid device
Yu. M. Bruck,L. G. Sodin +1 more
TL;DR: In this paper, a hybrid device comprising two identical hybrid transformers is studied both theoretically and experimentally, and several properties unknown even for the most advanced prior configurations are shown, such as identity of all inputs over a wide frequency range with respect to matching and isolation; a theoretically unbounded frequency range of isolation ; a possibility of obtaining arbitrary power division ratios from nought to infinity with the turns ratio varying over a rather restricted range.
