Applications of Pulse Phase Thermography
نویسندگان
چکیده
Recently, a novel approach was proposed which combines advantages of both pulse (PT) and modulated (MT) infrared thermography. In a nondestructive evaluation (NDE) perspective, the specimen is pulse-heated as in PT and the rnix offrequencies ofthe thermal waves launched into the specimen are unscrambled by perforrning the Fourier transform of the temperature time evolution over the field of view. Of interest is the maximum phase image with many attractive features: deeper probing, less infiuence to surface infrared and optical characteristics, rapid image recording (pulse heating, surface-wide inspection), possibility to inspect high thermal conductivity specimens. The proof-of-concept of this new approach called pulse phase infrared thermography (PPT) was demonstrated earlier [1].

متن کاملNondestructive Evaluation of Plexiglas Materials Using Lock-in and Pulse Phase Infrared Thermography
− Lock-in and pulse phase infrared thermography measurement techniques have been exploited for quantitative assessment of subsurface defects in a reference specimen made of Plexiglas. Radiometric thermal images were post-processed using a contrast approach in the frequency domain, allowing defect depth location to be resolved with a relative combined standard uncertainty of about 7% for thickne...
متن کاملNon-destructive Evaluation of Composites Materials by Pulsed-phase Thermography: Depth Inversion
This work is focused in the application of Pulsed-Phase Thermography (PPT) to non-destructive evaluation of composite materials. In this approach, the composite sample is heated by a thermal pulse briefly and recording the surface temperature decay with an infrared camera. Data processing and depth inversion is carried out by extracting and analyzing the response of the sample on the frequency ...

متن کاملInduction Thermography for Surface Crack Detection and Depth Determination
In the last few years, induction thermography has been established as a non-destructive testing method for localizing surface cracks in metals. The sample to be inspected is heated with a short induced electrical current pulse, and the infrared camera records—during and after the heating pulse—the temperature distribution at the surface. Transforming the temporal temperature development for eac...
