Title: | Linear algorithms for phase retrieval in the Fresnel region. 3. Validity conditions | Contributor(s): | Gureyev, Timur (author) ; Nesterets, Yakov (author) | Publication Date: | 2017 | DOI: | 10.1016/j.optcom.2017.08.039 | Handle Link: | https://hdl.handle.net/1959.11/23016 | Abstract: | We describe the relationship between different forms of linearized expressions for the spatial distribution of intensity of X-ray projection images obtained in the Fresnel region. We prove that under the natural validity conditions some of the previously published expressions can be simplified without a loss of accuracy. We also introduce modified validity conditions which are likely to be fulfilled in many relevant practical cases, and which lead to a further significant simplification of the expression for the image-plane intensity, permitting simple non-iterative linear algorithms for the phase retrieval. | Publication Type: | Journal Article | Source of Publication: | Optics Communications, v.405, p. 394-399 | Publisher: | Elsevier BV | Place of Publication: | Netherlands | ISSN: | 1873-0310 0030-4018 |
