Pulse modulated microwave and infrared thermography for superficial hyperthermia

Journal of Central South University, 2012
A 3D temperature field distribution of biological tissue for superficial hyperthermia using a pulse modulated microwave (PMMW) was presented. A 3D sliced homogeneous phantom was radiated by the PMMW and an infrared thermal imager was applied to image temperature distribution throughout the phantom.

Paving the way for the replacement of solder interconnections in power electronics by silver-sinter using pulsed infrared thermography

European Microelectronics and Packaging Conference, 2019
In this work we show the capabilities of non-destructive testing by pulsed infrared thermography (PIRT) on large-area silver-sinter layers. This method can achieve a similar reliability in detecting delamination as SAM and X-ray analysis.

Characterization of buried cylinders and spheres by pulsed infrared thermography

Journal of Applied Physics, 2005
A theoretical model to calculate the time evolution of the surface temperature of an opaque sample containing buried cylinders or spheres, after the absorption of a short light pulse, has been developed. To do this we first calculate the temperature of the material when it is illuminated by a modulated light beam. Then, based on the analogy between the

Multi-Pulse Infrared Thermography Applied to Improve Defect Detectability of Composites

Applied Mechanics and Materials, 2011
Traditional pulse infrared thermography uses a single pulse with high energy to heat the specimen. For deeper or smaller defects, more energy must be conducted into the specimen to improve the detectability, which also may cause thermal impact damage in particular for composites.

Investigation of honeycomb structure using pulse infrared thermography method

SPIE Proceedings, 2010
To reduce weight and improve strength in the aerospace industry, composite structure has gained popularity as a replacement for conventional materials and structures, such as adhesive bonding and honeycomb structure. Honeycomb structures composed by a honeycomb core between two facesheets are very common on aerospace parts.

Thermal characterization of rods, tubes and spheres using pulsed infrared thermography

Journal of Physics D: Applied Physics, 2007
In this work we analyse the accuracy of an extension of the flash method to measure the thermal diffusivity of rods, tubes and spheres, which was recently proposed by the authors. We have performed measurements in a wide set of calibrated samples of different sizes and we have found that a lower limiting size of the radius can be established for the ...
