Infrared temperature measurements in micro-channels and micro-fluid systems

This is a critical analysis of the application of infrared technique on devices in the range of tens to hundreds of micro-meters. Such devices are typical in micro-scale systems. Investigations performed during the last decade were used to analyze the specific features of micro-scale IR measurements. The method is illustrated by various examples of heat transfer determination using image analysis of the heater temperature as well as direct measurement of the liquid temperature.
