The 3D-Particle-Tracking-Velocimetry (3D-PTV) technique developed at the ETH Zürich is capable of measuring three-dimensional Eulerian and Lagrangian properties in three-dimensional fields of turbulent flows simultaneously. This technique is based on imaging illuminated flow markers with four steroscopically arranged CCD cameras Digital image processing, in combination with methods of digital photogrammetry and object tracking allows a reconstruction of the flow marker movement in an observation volume. The photogrammetric and physical basis of these techniques are presented comprehensively in Maas et al. [1993] and Malik et al. [1993]. We are reporting on the application of 3D PTV on the measurement of dispersion in a fully developed turbulent channel.
