A dusty plasma is formed by injecting micrometer-sized “dust” particles into a gaseous discharge of electrons, ions, and neutral particles. These dust particles typically acquire a high negative charge and form a massive plasma component that gives rise to many interesting novel structural and dynamical phenomena. A three-dimensional measurement of the microparticle motion is possible on the kinetic level of individual particles by stereoscopic imaging. Here, we checked different algorithms to reconstruct the three-dimensional particle trajectories. The algorithms were tested for artificial dust systems with respect to particle density, total particle number, and camera orientations. Finally, they were applied to real volumetric data measured on parabolic flights. Their performance in reconstructing particle trajectories in such dense dust clouds was analyzed. These trajectories will be used to reveal the underlying particle dynamics in further studies.
