Using X-ray computed tomography (CT) accurate 3D information about the foams structure is obtained, but the structural characterization of liquid foams, which feature structural changes, is still challanging. In this contribution a fast laboratory CT setup is presented allowing the acquisition of 3D data sets almost instantaneously. Reached limits for the CT system: ⢠15s measurement time for a complete 3D recording ⢠3.5 μm resolution for small objects (I.D. 10 mm) ⢠time-resolved structure characterization ⢠constant climate conditions (temperature, humidity) ⢠non-destructiv The suitability and possibilities of such a system for non-solidified foams and other porous materials are shown.en621006conference paper
