Abstract
In present study, to visualize a complicated flow field in a sphere packed pipe, we performed three-dimensional simultaneous measurements of velocity field around pebbles in water by an IM method and our proposed holography technique with two laser beams. As a result, we succeeded in the matching of the positions of tracer particles measured by two cameras. The obtained velocity field by two cameras exhibits the finer flow structures than that by one camera.
