Abstract

Thermal wave inspection is introduced with particular reference to the measurement and testing of surface coatings. Measurements are presented which demonstrate the effectiveness of the technique for assessing the thickness of plasma sprayed coatings and for detecting and imaging sub-surface defects. A new miniaturised testing system employing a high power semiconductor laser and a high collection efficiency infrared detector is described.
