Temperature of microfluids is greatly sensitive because of fast heat conduction and small heat capacity. The purpose of this study is development of a measurement system for the temperature field in a microfluidic device with high spatial and temporal resolution. Measurement method is laser induced fluorescence using Fluorescein with the temperature dependence of fluorescent intensity. In order to measure the step response temperature field, an image-intensified high-speed camera is utilized. Although this has low signal-to-noise ratio, it can be reduced by time- or phase- averaging scheme. Applying the synchronization mechanism, phase-averaged temperature data with time resolution of 500 μs can be obtained in this study.
