Active Thermography in Through-Life Engineering

2014
With the increased use of high-value components in aerospace industries, there is huge emphasis on reliability as their failure in service could lead to catastrophic failure of the system. Thus, there continues to be increasing dependency of such high-value components to undergo critical maintenance routines in order to reduce the probability of ...

Limitations of active dynamic thermography in medical diagnostics

The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005
The problem of validity of active dynamic thermography (ADT) imaging in medical diagnostics is discussed. Practical applications of ADT in medicine are known where synthetic pictures are defined and calculated for objective, quantitative data visualization as well as first attempts of thermal tomography based on ADT are published.

Using active thermography for defects inspection of flip chip

Microelectronics Reliability, 2014
Abstract With the development of electronics towards smaller, more compact, and increasingly complex, flip chip technology has been used extensively in microelectronic packaging, and disadvantages occur in traditional detection methods. It is indispensable to explore new methods for flip chip solder joint inspection.

Towards Material Classification of Scenes Using Active Thermography

2018 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2018
By briefly heating the local environment with a heat lamp and observing what happens with a thermal camera, robots could potentially infer properties of their surroundings. However, this form of active thermography introduces large signal variations compared to traditional active thermography, which has typically been used to characterize small regions

Thermography based on thermal activity measurements

Polymer Science U.S.S.R., 1978
A thermographic method was proposed, according to which in addition to even heating, the material is simultaneously sounded with transient temperature fields; the recording of these fields contains quantitative information about the coefficient of thermal activity of the material.

[Active thermography in the diagnosis of breast cancer].

Voprosy onkologii, 1990
Three procedures of active thermography were used in examination of 1301 patients with stage I-III breast tumors. The evaluation of their diagnostic effectiveness established their evident advantages over any method of passive thermography. Application of active procedures increased diagnostic accuracy by 9-15% and decreased the number of false ...

Medical Active Thermography — A New Image Reconstruction Method

2001
A new method of image reconstruction for active, pulse thermography is presented. Based on experimental results the thermal model of the observed object is proposed. Studies on thermal transients basing on the FEM object model are presented. Examples of reconstructed images are presented and described for phantoms and for in-vivo measurements. Possible

ACTIVE INFRARED THERMOGRAPHY TECHNIQUES FOR THE NONDESTRUCTIVE TESTING OF MATERIALS

2007
Active infrared thermography refers to the group of methods employed to inspect the integrity of materials or systems through the use of an external energy source and an infrared detector. The external stimulus can be of many forms such as warm or cold air, heat pulses, periodic thermal waves, or mechanical oscillations, e.g. ultrasounds.
