Detection of Subsurface Defects using Active Infrared Thermography
Active infrared thermography is a widely used technique in the field of nondestructive testing. The subsurface defects produce non-uniform heat dissipation and this phenomenon is captured by an infrared camera. The phase image gives a prominent description of the defects which are not visible in the captured image sequence. The effect of non-uniform heating and the variation in surface emissivi...
متن کاملAutomated measurement of concrete spalling through reinforcement detection
In emergency scenarios, immediate reconnaissance efforts are necessary. These efforts often take months to complete in full. While underway, building occupants are unable to return to their homes/businesses, and thus, the impact on the society of the disaster-stricken region is increased. In order to mitigate the impact, researchers have focused on creating a more efficient means of assessing t...
متن کاملDetection of rolling bearing degradation using infrared thermography
Our study deals with the quantification of the energy dissipated by a defect of spalling on the outside ring of a rolling bearing. A previous work showed a correlation between the thermal heating and the vibratory level generated by the progressive appearance of the defect. First, we propose a numerical model of the heat transfers In a second time, we developed an experimental setup. The result...
متن کاملA combined three-dimensional digitisation and subsurface defect detection data using active infrared thermography
In recent years, NonDestructive Testing (NDT) systems have been upgraded with three-dimensional information. Indeed, combine the three-dimensional and thermal information allows a more meaningful analysis. In the literature, the data for NDT and three-dimensional (3D) reconstruction analysis are commonly acquired from independent systems. However, the use of two such systems leads to error anal...
متن کاملDetection and characterization of buried landmines using infrared thermography
The application of infrared thermography to the detection and characterization of buried landmines (more generally, buried objects) is introduced. The problem is aimed at detecting the presence of objects buried under the ground and characterize them by estimating their thermal and geometrical properties using infrared measurements on the soil surface. Mathematically, this problem can be stated...
