Journal ArticleDOI
Lock-in thermography for nondestructive evaluation of materials
Datong Wu,Gerd Busse +1 more
TL;DR: In this paper, the phase sensitive modulation thermography (or "lock-in thermography") combines the advantages of photothermal radiometry with the fast technique of infrared imaging thereby revealing hidden defects in a short time.
Journal ArticleDOI
Optoacoustic phase angle measurement for probing a metal
TL;DR: In this paper, it is shown that using optoacoustic phase angle scanning rather than amplitude scanning enables precise measurements of subsurface structure in metal, for some applications the method can be an alternative to x-ray imaging.
Journal ArticleDOI
Nonlinear self-modulation and subharmonic acoustic spectroscopy for damage detection and location
TL;DR: In this article, a self-modulation mode of nonlinear acoustic vibrations of cracked defects has been analyzed and observed experimentally and attributed to the sum-frequency type resonance in a multi-degree of freedom system and include a subharmonic spectrum as a particular case.
Journal ArticleDOI
Subsurface imaging with photoacoustics
Gerd Busse,Allan Rosencwaig +1 more
TL;DR: In this article, the authors performed thermal wave imaging of subsurface features in a metal using, for the first time, piezoelectric detection, and presented photoacoustic magnitude and phase images.
Journal ArticleDOI
A local defect resonance to enhance acoustic wave-defect interaction in ultrasonic nondestructive evaluation
TL;DR: In this article, the model of a resonant defect was used for the selection of the wave frequency to enhance the excitation of the defect in nonlinear acoustics and ultrasonic thermography.
