Abstract
Digital holography has been applied to discriminate particles with different sizes in a capillary flow. With this objective, a specific matched filter, a Wiener Filter, has been applied to the complex amplitude distribution obtained from holograms recorded with a tilted illumination set-up. Different possibilities of applying such a filter have been considered, related to the Wiener Filter definition itself and to its application in a 3D or 2D approach. The tilted illumination set-up allowed us to generate a new 2D visualization of the 3D particle scattering that has been found very useful to help in understanding the difficulties in finding particle trajectories when particle tracking methods are applied.
