Infrared (IR) thermography technology is one of the leading non-destructive evaluation (NDE) techniques based on infrared detection. Infrared thermography, in particular, has the advantage of not only being used in non-contact mode but also provides full images, real-time inspection, and relatively fast results. These advantages make it possible to perform thermal imaging analysis of railway materials and/or components, such as brake disc simulation, monitoring of abnormal heat generation, and monitoring of temperature changes, during mechanical tests. This study introduces the current state of research on railway materials and/or components using IR thermography technology. An attempt was made to characterize the deterioration of electrical equipment of diesel electric locomotives using infrared thermal imaging techniques. In addition, surface temperature monitoring was performed during tensile testing of railway steels using a high-speed infrared camera. Damage evolution due to the hot spot generation of railway brake discs was successfully monitored using high-speed IR cameras. In this paper, IR thermal imaging technology, used as a non-destructive evaluation analysis in the railway field, was introduced, and the results of recent research are presented.

This study is aimed to analyze the thermal imaging patterns presented by infrared(IR) thermography at which the metal with internal defects are thermally heated. Through the knowledge of non-destructive testing which infrared thermography can be applied to detect the defects inside the materials, there are two materials experimented; one is stainless steel and the other is cast-iron. Thermally, each material of specimens is heated at the base of the material and kept with constant temperature, The artificial defects in the specimen are formulated. Under the shape and location of the defects, temperature profiles are also measured and validated using the computer simulation. It is concluded that the characteristics of thermal patterns obtained from IR thermography are consistent with those of measurement and computations.

Background The aim of this study was to examine the usefulness of infrared (IR) thermography in visualizing the dilation of the choke vessels in a delayed pedicled perforator flap rat model. Methods A three-territory island flap was designed and harvested on one side of the rat dorsum. The flap was divided into five regions. In the normal group (n = 8), IR thermal imaging was correlated with the postmortem arteriography for the location of angiosomes, linking patterns, perforator diameter, and temperature on each region. The delay group (n = 35) was divided into seven groups according to various delay periods. At different time intervals, the delay group was compared with the normal group according to link pattern and temperature on each region. Results IR thermal imaging showed that a white hotspot existed on the surface of each angiosome; the true anastomotic vessels manifested a continuous white band linking the white hotspots on angiosomes, whereas the choke vessels presented a red zone in between adjacent hotspots. After delay, the dilation of the choke vessels manifested itself as the replacement of the red zone between adjacent hotspots by the white band on IR thermography. In addition, the delayed flap presented a phenomenon of rise and fall in temperature over time. Conclusion IR thermography can accurately visualize the process of the dilation of choke vessels after a surgical delay. The chronological change in the IR thermal imaging combined with the temperature change in the delayed flap might be useful to determine the optimal delay period.
