Fast sizing of the width of infinite vertical cracks using constant velocity Flying-Spot thermography

Constant Velocity Flying-Spot thermography consists in scanning the sample surface by a focused CW-laser spot moving at constant speed. This technique was designed to study large surfaces in short times. In this work, we propose a method, based on a Flying-Spot thermography setup, to size the width...

This technique was designed to study large surfaces in short times. In this work, we propose a method, based on a Flying-Spot thermography setup, to size the width of vertical cracks by fitting the temperature profile along the line that contains the center of the laser spot and is perpendicular to the crack to its analytical expression.

This configuration is useful for in-line inspection in factories, for detecting and sizing cracks in real time, without stopping the production chain.
