Working Principles The system consists in: Processing An illumination source: high power pulse laser to generate a light sheet A seeding system: using particles contained in the atmosphere (natural) or spraying particles An optical part: 2 or more high speed / high resolution cameras, set perpendicularly to the laser sheet to capture the illuminated particles, by cross-correlation Post-processing and correlation tools Processing Two pictures are taken in a timeframe of 0,1µs: the illuminated particles are captured at t and (t + ∆t). As the particles move, the displacement is measured and the velocity vector is computed Example of a velocity field measured with the PIV technique Le Bourget June 2013
