Abstract

Phase-resolved Optical Doppler Tomography (ODT), an imaging technique based on low coherence interferometry, is presented as a tool to quantify the micro flow in microfluidic channel. Experiments using phase-resolved ODT to image and quantify Electroosmotic Flow (EOF) within a single microchannel are described demonstrating its utility in determining EOF in microchannels. Since it provides cross-sectional imaging of flow velocity, complex flow dynamics caused by microscale effects, such as electrokinetic flow, can be investigated and quantified using this tool.
