| Popis: | Contrôle non destructif par la thermographie infrarouge avec sollicitation de Laser CO2 et de la lampe halogène; International audience; This paper presents a NDT 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 μm. 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. |
