Infrared thermography based defect detection in ferromagnetic specimens using a low frequency alternating magnetic field

Study of the tensile behavior of AISI type 316 stainless steel using acoustic emission and infrared thermography techniques

“…During analysis of the acquired infrared images, a region of interest was selected for each frame and the average temperature of the pixels in the region was used for further analysis. This technique essentially reduces the experimental variations as temperature is measured over a large number of pixels simultaneously in real time and the average temperature is also computed in real time using Altair software [24,25].…”

Infrared thermography based studies on the effect of age on localized cold stress induced thermoregulation in human

“…Infrared thermography (IRT) is proved to be an excellent tool for non-invasive and real time monitoring of dynamic temperature variations. IRT has been widely used in the field of non-destructive evaluation [10][11][12][13], condition monitoring [14,15] and bio-medical applications [16,17] like breast cancer monitoring [18], diabetic neuropathy and vascular disorder [19], fever screening [20] etc. Due to its non-contact and dynamic temperature measurement capability, IRT is the most appropriate tool for monitoring thermoregulation induced subtle changes on skin temperature where other contact probes (like thermocouples or platinum resistance thermometers) may miss the localized dynamic temperature changes.…”

Infrared thermography based studies on mobile phone induced heating

“…For estimation of temperature rise, the ear and cheek regions of the subjects were considered and the average temperature values over the regions of interest were used for further analyses. This technique reduces experimental error as temperature of several points within a region of interest are simultaneously used for determining the average temperature which minimizes surface temperature fluctuations [22].…”

“…Radiance received by the camera is converted to an electrical signal in the infrared detector of the camera and the object temperature is determined using suitable calibration functions [19]. IRT has been widely used for non-destructive evaluation [19][20][21][22][23], condition monitoring [24] and bio-medical applications [25,26]. For bio-medical applications, in general, passive thermography is used without any additional heat sources.…”
