The PTR 8900: An Industrial Apparatus for Testing Materials by Infrared Photothermography
Infrared thermography, as a NDT tool, has been used intensively by nondestructive evaluation engineers for the testing of composite and plastic materials. Some application, vibrothermography [1,2], requires the use of a mechanical shaker to induce localized heating in the material, while some other, stimulated photothermography, requires the application of an external light source to create time-varying thermal patterns in the material under test [3,4].
