Information extraction from digital holograms for particle flow analysis

The goal of our project is to observe the distribution of steady and moving colloidal polystyrene particles within a micro-optofluidic canal system. To this end, we apply a classical in-line holographic setup with a magnifying telescope and a digital camera sensor. The capabilities of numerical hologram reconstruction and the subsequent image processing offer new possibilities concerning the digital hologram analysis. We demonstrate new concepts for a four-dimensional particle flow observation using a captured holographic video as well as the potentials for information extraction.
