LaVision‘s imaging and sensor systems provide market-driven measurement solutions for flow field imaging, combustion, spray and particle analysis and materials testing. Our diagnostic instruments are based on optical techniques such as Particle Image Velocimetry (PIV), Laser Induced Fluorescence (LIF), Light Scattering and Digital Image Correlation (DIC).
Shake-the-Box is the most advanced 3D Lagrangian Particle Tracking Velocimetry (PTV) method for densely seeded flows at highest spatial resolution. Compared to the voxel-based Tomo-PIV approach Shake-the-Box is a purely particle-based technique using an Iterative Particle Reconstruction (IPR) technique in combination with an advanced 4D-PTV algorithm using the time-information for track reconstruction. Shake-the-Box achieves a higher reconstruction accuracy at much faster processing speed compared with its TR-Tomo-PIV counterpart.
Beside different DaVis software packages FlowMaster systems for TR-Tomo-PIV and Shake-the-Box are using the same hardware.
