The fundamentals of Fourier Transform are presented, with analytical solutions derived for Continuous Fourier Transform (CFT) of truncated signals, to benchmark against Fast Fourier Transform (FFT. [] Key Method An existing method for Infrared Thermography, Pulse Phase Thermography (PPT), was benchmarked against a proposed method using polynomial fitting with CFT, to analyse cooling curves for defect identification in Non-Destructive Testing (NDT).


Quantitative subsurface defect evaluation by pulsed phase thermography: depth retrieval with the phase
Pulsed Phase Thermography (PPT) is a NonDestructive Testing and Evaluation (NDT&E) technique based on the Fourier Transform that can be thought as being the link between Pulsed Thermography, for
Time aliasing problem in pulsed-phased thermography
Pulsed phases thermography (PPT) is a well-known processing method of non-destructive testing (NDT) by infrared thermography. This method is based on the frequency analysis of the images obtained
Asynchronous Lock In Thermography of 3D Printed PLA and ABS samples
Lock-In thermography is a useful Non Destructive Technique (NDT) for enhanced detection of defects in components, as it amplifies the phase contrast where defects exist. This amplification was found
Pulsed Phase Thermography Approach for the Characterization of Delaminations in CFRP and Comparison to Phased Array Ultrasonic Testing
Pulsed phase thermography (PPT) is a well-established algorithm used for processing thermographic data in frequency domain with the aim to extract information about the defect size and depth.
Identifying the Geometry of an Object Using Lock-In Thermography
Two techniques of identifying the geometry of an object using LIT are discussed and Stochastic Gradient Descent can be used to determine the time when sufficient data have been collected from LIT measurement to generate the estimated geometry accurately.
Pulsed phase thermography reviewed
A general review of the Pulsed Phase Thermography technique is presented and the different types of uncertainties related to data acquisition and processing are identified.
Pulse phase infrared thermography
An 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
Infrared Thermography of Complex 3D Printed Components.
The possibility of using Infrared Lock-In Thermography (LIT) to estimate the thickness of a sample was assessed and shown to be accurate up to 1.8mm. LIT is a technique involving heating samples with
Review of pulsed phase thermography
Pulsed phase thermography (PPT) was proposed in 1996 to enhance results from pulsed thermography experiments. PPT can be thought as the link between pulsed thermography (PT) and lock-in thermography
