Universidad de Zaragoza High performance computing for a 3-D optical diffraction tomographic application in fluid velocimetry 2015 Access copy available to the general public Unrestricted Optical Diffraction Tomography has been recently introduced in fluid velocimetry to provide three dimensional information of seeding particle locations. In general, image reconstruction methods at visible wavelengths have to account for diffraction. Linear approximation has been used for three-dimensional image reconstruction, but a non-linear and iterative reconstruction method is required when multiple scattering is not negligible. Non-linear methods require the solution of the Helmholtz equation, computationally highly demanding due to the size of the problem. The present work shows the results of a non-linear method customized for spherical particle location using GPU computing and a made-to-measure storing format. info:eu-repo/grantAgreement/ES/DGA/T76 info:eu-repo/grantAgreement/ES/MINECO/DPI2010-20746-C03-03 info:eu-repo/grantAgreement/ES/MINECO/TIN2012-37483-C3 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.148 2015 OPTICS 14 / 91 = 0.154 2015 Q1 T1 1.91 2015 Atomic and Molecular Physics, and Optics 2015 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ortega, G.
