Pulsed-Active Microwave Thermography
2022 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2022Active microwave thermography (AMT) is a thermographic nondestructive testing and evaluation techniquethat utilizes an electromagnetic-based excitation with a subsequent infrared measurement of the surface thermal profile of the material or structure of interest.

Nondestructive Testing and Evaluation, 2023
Carbon fibre reinforced polymer (CFRP) composites are widely used in the aerospace industry; they are susceptible to impact damage from low-velocity impacts throughout their service life. Long pulse thermography (LPT) was proposed to detect defect in low-

Pulse phase infrared thermography
NDT & E International, 1996An approach is proposed which combines simultaneously advantages both of pulse (PT) and modulated infrared thermography. In a nondestructive evaluation perspective, the specimen is pulse heated as in PT and the mix of frequencies of the thermal waves launched into the specimen is unscrambled by performing the Fourier transform of the temperature ...

Intelligent Pseudo Solder Detection in PCB Using Laser-Pulsed Thermography and Neural Network
IEEE Sensors Journal, 2022Solder joints of printed circuit board provide the electrical and mechanical connections between electronic component and substrate. A pseudo solder inside the solder joint can reduce its electrical conductivity and often leads to crack initiation and ...

Pulsed phase thermography reviewed
Quantitative InfraRed Thermography Journal, 2004Pulsed Phase Thermography has considerably evolved since it was originally introduced in 1996. In this paper, a general review of the technique is presented. The different types of uncertainties related to data acquisition and processing are identified. Equivalence between discrete and continuous Fourier Transforms when applied to thermographic data is

Double pulse infrared thermography
NDT & E International, 2004Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an ...

This paper explores the implementation of Latent Low-Rank Representation (LatLRR) on pulsed thermographic data. LatLRR decomposes an image in the form of a linear association of three types of information: observed, unobserved and noise. This information

Pulsed eddy current thermography: system development and evaluation
Insight - Non-Destructive Testing and Condition Monitoring, 2010There is a need for fast and efficient techniques to inspect engineering structures and complex components such as aircraft turbine blades to identify potential sites of failure. Pulsed eddy current (PEC) thermography is a new inspection technique which allows the user to capture the eddy current distribution in a component or structure using infrared ...
