Particle Image Velocimetry
Low-speed Particle Image Velocimetry System
Resolve high flow velocities.
Particle Image Velocimetry (PIV) is a non-intrusive laser optical measurement technique based on the processing of pairs of time delayed images, used for measuring flow velocities. Low-speed PIV allows lower repetitive rates and features low inter-frame times to enable the resolution of high flow velocities. Using a high-power laser the system can illuminate sheets or volumes.

High-speed Particle Image Velocimetry system
Time-resolved velocity in 2D and 3D.
The high-speed Particle Image Velocimetry (PIV) System allows the acquisition of time-resolved velocity fields in 2D and 3D space. Typical high-speed applications begin at 1000 Hz data and may reach tens of kHz at the expense of the spatial resolution. Special high-speed cameras are required.
