Mikro Particle Image Velocimetry (µ-PIV)

  • Description:

    The device measures velocity fields in flows in the micrometer range.

    The micro flow to be investigated is mixed with fluorescent micro particles. A
    Double pulse Nd:YAG laser is focused on the sample through an epifluorescence microscope. With the help of
    of a synchronization unit, two images are acquired during the laser pulses in short time intervals.
    Distance recorded. The PIV images are then processed with PIV algorithms (cross correlation)
    evaluated.
