Description

In a previous report, some of the authors have described the basic experimental technique for flying laser spot thermal wave IR imaging, and demonstrated its potential usefulness for the detection of closed vertical cracks [11. The objective of the present work is to provide a theoretical description of the temperature distribution from a Gaussian-shaped surface heat spot, scanned at constant speed, and to compare the predictions of that theoretical description with temperature distributions measured experimentally with our thermal wave flying spot imaging system.
