Defect Automatic Identification of Eddy Current Pulsed Thermography [PDF]
Journal of Sensors, 2014 Eddy current pulsed thermography (ECPT) is an effective nondestructive testing and evaluation (NDT&E) technique, and has been applied for a wide range of conductive materials. Manual selected frames have been used for defects detection and quantification. Defects are indicated by high/low temperature in the frames. However, the variation of surface

Detection of Differentiated Tissue with Pulse Thermography
Proceedings of the 2014 International Conference on Quantitative InfraRed Thermography, 2014 We report on the study of the relationship between the length of the pulses and the depth of the boundary to be detected in thermally transmissive tissues within the therapeutic window, red to IR spectral range. We use a three-layer theory to predict the possibility of detection of an abnormal growth. 1.
