Thermography measurements allow to detect the defects that may appear undersurface of details with protecting covering. Subsurface defects in the sample have been detected using the high resolution thermal imaging camera FLIR SC7000. To introduce additional energy in a researched sample, a scanning hot air (about 110°C) nozzle is applied (a patent application P.403346). The hidden defect causes...

Although diagnostic criteria for chondromalacia patellae exist, the disease is often accompanied by physical signs which are limited or non-diagnostic. Thermographic examination was performed in 157 patients with clinical diagnosis of chondromalacia patellae in 86 patients after surgical treatment for chondromalacia, and in 308 controls. Thermography can help the clinicians in establishing the ...

In this paper, a technique is presented to detect micro-cracks on photo-voltaic cells by infrared thermography. The originality of the system comes from the thermoelectric stimulation used to generate thermal transients at micro-crack locations. These thermal transient are picked-up by an infrared cameras for further detection.

Surface temperature drives many ecological processes and infrared thermography is widely used by ecologists to measure the thermal heterogeneity of different species' habitats. However, the potential bias in temperature readings caused by distance between the surface to be measured and the camera is still poorly acknowledged. We examined the effect of distance from 0.3 to 80m on a variety of th...

An infrared thermography equipment is used to measure the temperature rise at the rear surface of a sample submitted to the pulse irradiation of a flash source, in order to derive simultaneously two thermal properties of the sample. The Levemberg Marquadt technique is used to match the experimental data to the analytical model. Care is taken to tune sample features and the experimental set-up. ...

Infrared thermography is a nondestructive evaluation technique aimed to the detection of surface temperature variations related to the presence of subsurface defects. Several inspection techniques have been developed over the years with basically two approaches, lock-in thermography and pulsed thermography. These two techniques are based on the principle of heat diffusion and thermal wave refle...

BACKGROUND The purpose of the present study was to evaluate the sensitivity, specificity, and accuracy of thermography in identifying patients with temporomandibular dysfunction (TMD). MATERIAL AND METHODS The study sample consisted of 50 patients (27 women and 23 men) ages 19.2 to 24.5 years (mean age 22.43±1.04) with subjective symptoms of TMD (Ai II-III) and 50 patients (25 women and 25 me...

T he major reason for monitoring intraoperative temperature is for detection of fever, malignant hyperthermia, and hypothermia. Inadvertent hypothermia-defined by an absolute core temperature <36”C-is by far the most common perioperative thermal disturbance. However, hypothermia may be difficult to evaluate using liquid-crystal thermography, because skin temperatures are l-4°C less than core te...
