Equipment Name: La Vision Micro Particle Image Velocimetry
General Description: Micro-Particle Image Velocimetry (PIV) system is designed to measure velocity fields of particle seeded flows with micron scale spatial resolution using PIV techniques. The light source is typically a double pulsed Nd:YAG laser that is coupled through an optical fiber into a fluorescence microscope and focused with a high numerical aperture on a microfluidic device.
The microflow is seeded with fluorescent particles. A microscope lens collects the particle signal that has a longer wavelength than the illuminating light. This signal is separated from the laser light by a filter cube and is recorded by a double-frame CCD camera. The double frame images are evaluated with conventional PIV algorithms.
