Title: | Quantitative diffraction-enhanced x-ray imaging of weak objects | Contributor(s): | Nesterets, Yakov (author); Gureyev, Timur (author) ; Paganin, David (author); Pavlov, Konstantin M (author) ; Wilkins, S W (author) | Publication Date: | 2004 | DOI: | 10.1088/0022-3727/37/8/016 | Handle Link: | https://hdl.handle.net/1959.11/3529 | Abstract: | Theoretical aspects of quantitative diffraction-enhanced imaging of weak objects are considered using the Fourier optics approach. The amplitude and phase transfer functions are introduced by analogy with the well-known case of in-line (holographic) imaging. The inverse problem of the reconstruction of the phase and amplitude of the incident wave from recorded images is solved in the case of non-absorbing objects and objects consisting of a single material and in the general case of objects with uncorrelated refraction and absorption characteristics. A comparison is given between the solutions to the inverse problem obtained using the new formalism and the geometric-optics approximation. | Publication Type: | Journal Article | Source of Publication: | Journal of Physics D: Applied Physics, 37(19), p. 1262-1274 | Publisher: | Institute of Physics Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1361-6463 0022-3727 |
