Abstract

Creating and monitoring micro-scale thermal transfer in micro-structured thin polymer films is presented in this study. Thermal imaging is captured using IR camera equipped with optics designed for the mid- and long- IR wavelengths. The non-contact thermal imaging method is preferred to visualize the distribution of temperature and characterizes the thermal properties of complex multi-component/layered structures of thermal functioning materials. The work is to present a method for thermal wave imaging that is applied to measure the thermal diffusivity of the micro-structured polymer thin films using a modulated laser-diode spot heating irradiated to the rear surface of the film, observed at different modulation frequencies. The procedure is based on the micro-scale thermography and the analysis is based on the computational phase lock-in system for the temporal evolution extracted from the sequence of infrared image. The in-plane surface profiles of the amplitude and phase are precisely calculated and the principle for eliminating the effects of heat loss is examined.
