【 摘 要 】

The possibility to perform the tomography of irregularly-shaped rough particles in a flow using multi-view interferometric imaging is investigated. Combining three perpendicular angles of views, we reconstruct a family of possible 3D-shapes from speckle patterns. The estimation of an error parameter enables the elimination of erroneous 3D-shapes to obtain a more accurate estimation of the particle's volume. The principle is tested and confirmed experimentally by analyzing a set of three interferometric images of programmableparticles generated by a digital micromirror device.
