Abstract The possibility to perform the tomography of irregularily-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 analysing a set of three interferometric images of “programmable” particles generated by a digital micromirror device.

流动中粗糙粒子断层扫描的干涉成像：案例研究

摘要 研究了使用多视图干涉成像对流动中形状不规则的粗糙颗粒进行断层扫描的可能性。结合三个垂直的视角，我们从散斑图案重建了一系列可能的 3D 形状。误差参数的估计能够消除错误的 3D 形状以获得更准确的粒子体积估计。通过分析由数字微镜设备生成的一组三个“可编程”粒子的干涉图像，通过实验测试和确认了该原理。
