Universidad de Zaragoza (orcid)0000-0002-2930-7431 Three-dimensional particle size and position measurement by linear complex amplitude Wiener filtering; 35473233 2022 Access copy available to the general public Unrestricted Digital in-line holography (DIH) combined with a Wiener filter has been applied to measure particle size and position in the flow inside a capillary model, seeded with magnetic particles (3µm) and with solid opaque particles that simulated red and white cells. The proposed filtering process takes advantage of the linearity implicit in the numerical reconstruction of the object complex amplitude. A modified DIH set-up, with a tilted illumination beam, was used as it presents two main advantages: it solves the twin image issue associated to in-line holography and increases the out-of-plane resolution. Experiments show that the proposed method discriminates particles within a range from 3 to 30µm with a sensitivity of 0.5µm. © 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement info:eu-repo/grantAgreement/ES/DGA-FEDER/E44-20R info:eu-repo/grantAgreement/ES/MICINN/PID2020-113303GB-C22 info:eu-repo/grantAgreement/ES/MICIU/BES-2017-080924 info:eu-repo/grantAgreement/ES/MICIU/DPI2016-75791-C2-2-P/1-P info:eu-repo/grantAgreement/ES/UZ/UZ2020-CIE-04 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.8 2022 OPTICS 30 / 99 = 0.303 2022 Q2 T1 1.138 2022 Atomic and Molecular Physics, and Optics 2022 Q1 6.9 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lobera Salazar, J.
