Volumetric and Tomographic Particle Tracking As a fluid dynamicist, your interest extends beyond velocity fields. You want the complete time resolved Lagrangian particle history of your flow - Volumetric and Tomographic Particle Tracking provides this for you. Volumetric and Tomographic Particle Tracking When the acquisition of Lagrangian information is of relevance to your research, our Particle Tracking methods provide the solution. Volumetric Particle Tracking is the entry point into the world of Volumetric Velocimetry. With moderate seeding density, this tracking works with only two...

A few of the many innovative and unique features are: Illumination - as sharp as a razor Conventional light sheet optics provide a Gaussian intensity distribution with fading intensity toward the edges; thus the measurement volume is not well defined and the particles are unevenly illuminated. Our unique optics provide illumination with sharp edges and an intensity that does not drop off towards the edges. This is accomplished without sacrificing the total energy output by knives or apertures. Telecentric imaging - focal depth as deep as the ocean Particle detection and tracking techniques...

Least Squares Matching Have you ever been disappointed with the large errors in velocity gradients derived from PIV data? Least Squares Matching offers the solution by directly providing the velocity gradient tensor without the need for derivation from the velocity field. Least Squares Matching The limitations of two and three-dimensional cross correlation based PIV are well known. Cross correlation is only sensitive to translational displacement, and velocity gradients must be derived using difference schemes that introduce additional noise. LSM on the other hand, is the next generation...
