Title: | Unambiguous reconstruction of the complex amplitude reflection coefficient of a laterally homogeneous crystal using analyser-based phase-contrast imaging | Contributor(s): | Vine, David (author); Paganin, David (author); Pavlov, Konstantin M (author) ; Podorov, S G (author) | Publication Date: | 2007 | DOI: | 10.1107/S0021889807021097 | Handle Link: | https://hdl.handle.net/1959.11/3483 | Abstract: | A theoretical approach is developed to invert analytically a hard X-ray analyser-based phase-contrast image of a known weak object to recover the complex amplitude reflection coefficient (ARC) of a laterally homogeneous crystal. Numerical simulations test the method to recover the ARC from two systems of interest: a thick perfect crystal and a linearly strained thin film. For the latter model, a kinematical diffraction approximation was used to recover the one-dimensional deformation profile from the ARC. | Publication Type: | Journal Article | Source of Publication: | Journal of Applied Crystallography, 40(4), p. 650-657 | Publisher: | Wiley-Blackwell Publishing Ltd | Place of Publication: | United Kingdom | ISSN: | 1600-5767 0021-8898 |
