Accurate measurements of the thermal diffusivity of thin films and thin filaments using lock-in thermography
In lock-in thermography the thermal diffusivity can be obtained from the slope of the linear relation between the phase of the surface temperature and the distance to the heating spot. However, in the case of thin samples, the linearity is not found. In this work we identify heat conduction to the surrounding gas as the mechanism responsible for the lost of linearity. Accordingly accurate measu...
متن کاملFlying Laser Spot Thermography for the Fast Detection of Surface Breaking Cracks
We report on recent developments in the detection of surface breaking cracks using flying laser spot thermography. Application of an infrared camera for mapping the thermal radiation after excitation with a diode laser equipped with an optical scanner allows us to examine a surface containing cracks in an entirely non-destructive, contactless and fast way, without even moving the camera. We dev...
متن کاملQuantitative assessment of aerospace materials by active thermography techniques
The inspection of aerospace materials such as composites, honeycomb structures, ceramics and GLARE has been the subject of many studies in the NonDestructive Testing and Evaluation (NDT&E) community. Active thermography techniques have shown to be an interesting alternative or complementary to other classical NDT&E techniques. Nevertheless, the different techniques perform differently depending...
متن کاملQuantitative Thermal Diffusivity Imaging of Disbonds in Thermal Protective Coatings Using Inductive Heating D
Problems of adherence of thermal protective coatings to aerospace structures have become important with their use on vehicles such as the space shuttle and for jet engine turbine blades. In these structures a dielectric coating which acts as a thermal barrier. is bonded to a conductive substrate. Failure of these coatings to adhere to the substrate can result in catastrophic failure of the vehi...
متن کاملFlying Laser Spot Thermal Wave Ir Imaging of Horizontal and Vertical Cracks
As an extension of the work of Kuo et al[l], we have developed a "Flying-Spot" lasersource/IR-detector camera in which the focal point of an unmodulated heating laser is moved at constant velocity across the sample while the image point of an IR detector is scanned at the same speed at a point just behind the laser beam. The detector is thus looking at the "thermal wake" of the heated spot. The...
