|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:||The Netherlands||ISSN:||1873-0310
