| Outline of Final Research Achievements |
Presently, three-dimensional particle motions are measured by using the Doppler phase-shifting holography. By the Doppler effect caused by the moving particles, the longitudinal velocity can be calculated from the Doppler beat frequency. Moreover, with the use of micro PIV for the in-plane velocity measurement, three-dimensional velocity measurement has been achieved.
First, the discrete particles with different velocities are measured simultaneously. Then, the same measurement was done with the expanding optics. Thus, the three-dimensional velocity measurement of the particles in the micro channel will be possible with the single camera observation under microscopy.
