Three-Dimensional Particle Tracking Velocimetry using a Single Time-of-Flight Camera

Time of Flight (ToF) cameras are a type range-imaging camera that provides three-dimensional scene information from single camera. This paper assesses the ability ToF technology to be used for threedimensional particle tracking velocimetry (3D-PTV). Using commercially available various aspects 3D-PTV considered, including: minimum resolvable size, environmental factors (reflections and refractive index changes) time resolution. Although it is found an off-the-shelf not viable alternative traditional measurement systems, basic measurements shown with large (6mm) particles in both air water demonstrate future potential use as this develops. A summary necessary technological advances also discussed.
