Imagerie de la vélocimétrie des particules (PIV)

Nos systèmes d’imagerie sont utilisés pour la mesure de la vélocité des flux de liquide et de gaz. En plus de fournir des PIV 2D conventionnels, des stéréos PIV, des micro PIV et des systèmes à haute vitesse, Oxford Lasers fournit aussi des lasers à haute fréquence et à impulsions doubles, des caméras et des logiciels PIV.

Vector Analysis is a very powerful technique for performing flow velocity measurements in air or water or for measuring spray droplet / particle velocity using VidPIV - PIV Software . In addition, the same hardware can be used for flow visualization and Particle Tracking Velocimetry (PTV).

Vector Analysis Systems from Oxford Lasers offer an unparalleled choice for flow measurement / visualisation. The VisiVector range includes standard 2d / planar, stereo / 3D, high speed / time resolved and micro.

Oxford Lasers also provides components and accessories including lasers, cameras, software and light delivery.

• 2D / Planar provides velocity measurement in a single plane, normally at frame rates up to 15 image pairs/second.
• Stereo / 3D systems use a pair of cameras to provide stereo / 3D measurement of velocity.
• High speed / time resolved products use high speed cameras and high repetition rate, double pulse lasers to take thousands of image pairs per second to provide time resolved velocity data.
• Micro systems view via a time resolved system and provide flow measurement in microfluidic devices.
