Thermal Wave Imaging

Abstract

Several aspects of thermal wave techniques for imaging defects and characterizing material properties have been studied during the course of this contract. Among the thermal wave detection techniques which were investigated are the mirage-effect (optical probe beam), the thermoacoustic effect, photothermal reflectance, and infrared (IR) video lock-in imaging. Both experiment and theory have been studied, and applications made to crack- detection, layered structures and delaminations, semiconductor devices, and contactless measurements of thermal diffusivities. Keywords: Thermal wave imaging; Nondestructive evaluation; Materials characterizations.
