Non-invasive mapping of fluid temperature and flow in microsystems

Currently available temperature and fluid flow measurement methods have shown limitations in microscale systems. This research concerns the development of a non-invasive optical measurement technique and sensor for mapping two-dimensional temperature fields and, ultimately fluid flows. The system is based on the Shack-Hartmann wave-front sensor. Analytical considerations underlying the mapping technique and preliminary experimental results are presented. Two experimental rigs involved in this study are also discussed.
