TSI PLIF System Concentration and Velocity Measurement

TSI PLIF System Concentration and Velocity Measurement

The TSI PowerView based Global Liquid Concentration Analyzer (GLCA) and Global Liquid Mixing Analyzer (GLMA) are designed to meet the research needs of anyone needing a fully integrated, turn-key system that provides global species measurements in mixing, materials processing, heat/mass transfer, and other liquid based environments. Both systems use planar laser-induced fluorescence (PLIF) to provide global concentration measurement of the species of interest in the laser sheet region.

Both systems are composed of three integrated sub-systems: the Illumination System, the Imaging System, and the Display and Analysis System. The only difference is that the GLMA system provides simultaneous concentration AND velocity fields, to fully characterize micro-fluidic mixers, reactors, and numerous other processes. GLMA and GLCA systems are composed of three sub-systems: The Illumination Sub-system includes a Nd:YAG laser, lenses, and beam delivery optics to get the light sheet where you need it. The Imaging Sub-system features one (GLCA) or two (GLMA) TSI PowerView cameras with the right resolution, sensitivity, and speed required for your application.

The laser and camera are controlled by a TSI LaserPulse Synchronizer, which is fully integrated into the revolutionary INSIGHT 4G Global Imaging software platform, which not only provides data analysis and display capabilities, but also directly controls the hardware components for simple system operation.
