Abstract

A novel high-speed scanning micro particle image velocimetry system has been developed in order to provide time-resolved, pseudo-three-dimensional flow-field information. The focal plane is moved rapidly in the out-of-plane direction by changing the optical length using a rotating disc having glass windows with different thicknesses. In the present prototype system, the extent of the scanning depth is 50 $μ$m and the maximum scanning frequency is 100 Hz. Through a series of experiments in a two-dimensional microchannel, it was found that the velocity data are in good agreement with the analytical solution. The fluctuation in the flow rate delivered by a syringe pump is successfully measured with the present system. This demonstrates the applicability of the present scanning system for unsteady flow measurements.
