La Vision

The PIV Systems from La Vision measure the flow’s instantaneous velocity, determining the distance covered by particles within the time between two pulses of the laser. A plane in the flow in movement is illuminated by a “plane laser beam” and the particles positions in this plane are registered by one CCD camera. A fraction of second after the first “plane laser beam”, another “plane laser beam” illuminates the same plane in the flow and then the CCD camera captures another image recording new particles positions. An analysis software captures and analyses the particles displacements from the region in both images and calculates the velocity in hundreds or thousands of locations with extreme rapidity and trustworthiness.



By this way the flow proprieties as vorticity, turbulence and tension reasons can be obtained for the entire studied region, enabling average statistical values and of higher order to be determined.
