摘要：

This paper presents a NOT by a CO2 Laser infrared thermography applied to defect detection in CFRP. The CO2 Laser is an infrared laser with the wavelength of 10.6 mu m. This excitation has a controllable heating beam by a geometric relation D = 0.01575.d, which allows to heat the samples at a specific position (placed at the distance "d") and area (of a diameter "D"). The PPT interpretation principle was used to reduce the non-uniformity's effect of the excitation causing inhomogeneous heat. The test with this excitation is much faster than the tests with conventional lock-in thermography method. (C) 2014 Elsevier Ltd. All rights reserved.
