LaVision provides a wide range of different volumetric analysis methods such as Tomographic PIV, Tomographic PTV and 3D-PTV, all based on identical hardware and experimental setup. LaVision's unique Tomographic PIV allows the measurement of flow fields at particle densities surpassing all other volumetric flow measurement techniques, giving the maximum amount of information from a single recording. After the tomographic reconstruction one is free to do Eulerian vector calculation on a regular grid (Tomographic PIV) or Lagrangian tracking of individual particles (Tomographic PTV). Direct particle tracking, with 3D-PTV, delivers individual particle velocities from ten thousands of particles in only a few minutes of analysis time.LaVision?s volumetric systems cover the whole range of measurement volumes: from cubes to thin volumes, from small volumes of only a few cubic millimeters to large volumes of several liters. Both, low speed cameras for instantaneous high resolution measurements or high speed cameras to do time resolved measurements can be used for imaging. As part of the volumetric measurement techniques LaVison's unique Volume Self-Calibration allows the usage of only one single view of a 3D calibration target to calibrate the complete volume at once. An adjustable Volume Optics is used for easy illumination of the desired measurement volume.
