Applications of Pulse Phase Thermography
, 1997 Recently, a novel approach was proposed which combines advantages of both pulse (PT) and modulated (MT) thermography. In a nondestructive evaluation (NDE) perspective, the specimen is pulse-heated as in PT and the mix of frequencies of the thermal waves launched into the specimen are unscrambled by performing the Fourier transform of the temperature ...

Pulse Phase Thermography: Impact Damage Retrieval [PDF]
Materials Today: Proceedings, 2018 Composite materials used as structural member in aircraft, vehicles, yachts and vessels, require high performance mechanical properties so their quality control and inspection is essential for security, maintenance and evaluation. Impact damage, as it occurs on the interlaminar scale, is hard to reveal with standard NDT methods.

Lock-in and pulsed thermography for solar cell testing [PDF]
Applied Optics, 2018 Inspection of solar cells is an important part of their production process because even small defects can cause a significant drop of a whole photovoltaic module performance. LED illuminated lock-in (LEDILIT) and flash-pulse thermographic techniques (FPT) were compared in this study. Lock-in methods are more commonly used for solar cell inspection. The
