Abstract

As the imaging speed of Optical Coherence Tomography (OCT) and Optical Doppler Tomography (ODT) increases, a new horizon to access dynamical systems with fast transients will be open near future. The objective of this research is to demonstrate its potential to measure simultaneously the structure and velocity information of dynamical systems. Transient two-fluid mixing in microfluidic devices are good examples to display clearly the advantages of ODT over other techniques. Laminar dispersion in a serpentine microchannel with a Y-shape inlet was investigated using OCT and ODT. It was shown that OCT/ODT is not only a visualization method but also a methodology to characterize important physics: streamwise velocity, secondary streamline, sedimentation time scale, shear dispersion. To demonstrate the capability of OCT/ODT, transient mixing was observed and three-dimensional imaging was performed.
