Abstract

In order to study Lagrangian properties of turbulent flows a compact digital in-line holography setup in combination with a high-speed camera was used to track time resolved 3D particle positions. First measurements on a vortex flow show reliable trajectories confirming the expected flow field. However, the use of a non-optimised camera and the poor depth resolution of the system lead to problems in tracking particles over long periods in time.
