PIV stands for Particle Image Velocimetry. It is a technique for measuring and recording instantaneous velocity vectors in a cross-section of a flow. Two velocity components are measured. By using a stereoscopic approach all three velocity components can be recorded, which results in 3D velocity vectors for the whole area. CCD cameras capable of capturing two images with extremely short inter-frame time (in the range of a few microseconds). Used together with specialized computer tools, the images result in real-time velocity maps.
JAI cameras that have a P.I.V mode are :
