Dual Frame PIV/PVT Camera

The LaVision FlowMaster system family evaluates three-dimensional velocity vector fields from scattered light patterns of particles or droplets seeded into the flow (liquid or gas). Techniques like Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) are supported. LaVision's FlowMaster camera systems can record two successive images within min. time <100 ns for ultrafast cross-correlation and speeds up to Mach 4. The PIV cameras offer highest sensitivity and allow the use of very small particles (or droplets). An image field of up to 16 million pixels combined with up to 14 bit dynamic range gives an unsurpassed spatial resolution. Programmable precise timing sequences in combination with flexible and speedy software evaluation complete the package.
