Particle path based image velocimetry has been developed for 3D volumetric velocity measurement of fluid flows. The proposed method is basically based on the tomographic reconstruction of 3D particle paths by using multiple camera views of long exposure particle images. Particle path based image velocimetry was popular in the early days of 2D PIV but went out of use rapidly because of its inherent issues like intersection of particle paths and directional ambiguity. But in the present work, this technique is further exploited by using new techniques based on the tomographic reconstruction of 3D particle paths. The velocity recovery results of this new approach are compared to those of the conventional 3D tomographic particle tracking velocimetry using two instantaneous particle images at different instants.
