This research dissertation focuses on the developments of tomographic PIV (tomo-PIV)for the measurement of turbulent flows (Elsinga et al. 2006). It is based on thetomographic reconstruction of a volumic intensity distribution of tracer particles fromprojections recorded on cameras. The corresponding volumic distributions are correlatedto obtain 3D displacement fields. The present work surveys the state of advancement ofthe research conducted on this technique and the main issues it has been confronted withso far. The main research focus was on tomographic reconstruction. Indeed, its mainlimitation is the appearance of ghost particles, ie reconstruction noise, which occurswhen high tracer concentrations are required for high spatial resolution measurements.
