Micro PIV is a modification of the PIV done in order to measure the velocity fields at micron scale. A typical setup consists of a double pulsed laser, epi-fluorescent microscope and filters, CCD camera, microflow seeded with florescent partices. The double frame images are evaluated with conventional PIV algorithms. The correlation of the particles motion between two laser pulses provides the spatial velocity field. High accuracy results are reported by use of Micro PIV.
