A new signal processing algorithm of pulsed infrared thermography

Infrared Physics & Technology, 2015
Abstract A new signal processing algorithm combining Markov and principal component analysis (PCA) algorithm, which was named as Markov–PCA algorithm, was proposed to process the pulsed infrared thermography. First, the image sequence was reconstructed using Markov algorithm, then the original complex data dimensionality was reduced using PCA ...

Study on detecting CFRP composites using pulsed infrared thermography

Proceedings of SPIE, 2011
Composite sandwich structure has been widely used in aerospace due to its lightweight, high stiffness and strength. The quality of the structure is crucial to durability and structural integrity of the rehabilitated the structure, Delaminations, debonding and water ingressing to honeycomb are typical defects in the structure.

Pulse phase infrared thermography

NDT & E International, 1996
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 PT and the mix of frequencies of the thermal waves launched into the specimen is unscrambled by performing the Fourier transform of the temperature ...
