Continuous Fourier Transform: A practical approach for truncated signals and suggestions for improvements in thermography
K. H. H. Goh
The fundamentals of Fourier Transform are presented, with analytical solutions derived for Continuous Fourier Transform (CFT) of truncated signals, to benchmark against Fast Fourie…
Identifying the Geometry of an Object Using Lock-In Thermography
Xiao Tian, Meng Yuan Yin, Kok Hin Henry Goh
Lock-in Thermography (LIT) is a type of Infrared Thermography (IRT) that can be used as a useful non-destructive testing (NDT) technique for the detection of subsurface anomalies i…
Infrared Thermography of Complex 3D Printed Components
Ming Hin Wong, Kok Hin Henry Goh
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 h…
Asynchronous Lock In Thermography of 3D Printed PLA and ABS samples
K. H. H. Goh, Q. F. Lim, P. K. Pallathadka
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 ampli…
