Measurement of Lagrangian Particle Trajectories by Digital in-line Holography
A digital holographic in-line setup was used to track particles in a small turbulence chamber. Different particle validation methods have been tested to filter out speckles and to enhance accuracy of the longitudinal particle coordinates. In first measurements particle trajectories were measured and visualized together with fitted spline curves. A pronounced decrease of the standard deviation of the particle coordinates with respect to their spline curves was achieved.
