Considering the influence of fixing method component in system on its results ultrasonic infrared thermography testing, detection experiments cracked plat structure with at one end and two ends are carried out through different methods equivalent structure. The show that for same to be detected, more bounds fixed, degrees freedom restricted, less energy is dissipated during inspection process, ...

A new experimental approach based on infrared thermography is proposed in this paper for studying crystal growth kinetics in undercooled melts. The crystallization of a thin sample of an undercooled melt at constant bulk temperature is induced by a small crystal seed and the growth of the solid phase is observed using infrared camera. The recorded thermal images allow determining the position o...

This paper presents a method for detecting defects in reinforced concrete structures by using the method of active infrared (IR) thermography. Non-destructive testing using infrared (IR) thermography consists of thermal stimulation of the object of interest and monitoring of the surface temperature variation during the transient cooling or heating process. The paper includes short descriptions ...

The subject of investigation is a set four artificial heart valves made electrically conductive material, namely the alloy Ti-6Al-4V. Notches defined geometry with gradually increasing depth were formed on these BSCC (Bjork-Shiley Convexo-Concave) valves. These defects are created so-called output strut, which serves as support mechanism for controlled movement occluder disc and they have been ...

In this study, UV-curable urethane acrylate UA synthesized and then characterized by FTIR and HNMR. For better dispersion of nanoparticles in polymeric matrix, nano Al2O3 was modified by silane coupling agent and then its nanocomposites were prepared. The characteristics of synthesized nanocomposites were analyzed by TGA, DMA and infrared thermography. The results signify that adding nano Al2O3...

A novel measurement technique, based on infrared thermography, has been applied for characterizing the thermal properties of paper with high spatial resolution. The technique is termed as ‘active thermography’ since the temperature response of a paper sheet is observed and analyzed with respect to an external periodic heating. Through the analysis of the temperature response of the paper surfac...

This paper is about the development, uses and advantages of infrared thermography. Its principles had already been used by old civilizations as a manner of diseases diagnosis. The discovery of the infrared waves and its heating power happened on 1800, but its use in modern Medicine as a diagnosis method was only possible because of the scientific and technological development demanded by the Gr...

This work aims to study the usability of infrared thermography in swimming for the purpose of quantifying the influence of the swimming style on the cartographies of cutaneous temperatures of a swimmer. Only one subject took part in the experimental protocol, who was to accomplish a 4 x 100 m 4 medley. Thermal acquisitions followed by one period of recovery with return to thermal balance were c...

We present a thermal conductivity measurement method for laser crystals based on thermal mapping of the crystal face by an infrared camera. Those measurements are performed under end-pumping of the laser crystal and during laser operation. The calculation of the fraction of pump power converted into heat is therefore simplified, and it is possible to link easily the temperature in the crystal t...
