0. Abstract In this paper we propose a simple enhancing protocol for pulsed infrared thermography. The method is based on stimulating the specimen with two heating pulses separated by a short time interval delta. This approach was tested on several specimens of low and high thermal diffusivity and showed to provide higher thermal contrasts when an optimum interval delta is chosen. The observed ...

This paper is about the development, uses and advantages of infrared thermography. Its principles had already been used by old civilizations as a manner of diseases diagnosis. The discovery of the infrared waves and its heating power happened on 1800, but its use in modern Medicine as a diagnosis method was only possible because of the scientific and technological development demanded by the Gr...

This work aims to study the usability of infrared thermography in swimming for the purpose of quantifying the influence of the swimming style on the cartographies of cutaneous temperatures of a swimmer. Only one subject took part in the experimental protocol, who was to accomplish a 4 x 100 m 4 medley. Thermal acquisitions followed by one period of recovery with return to thermal balance were c...

Detecting Carotid Occlusive Disease by Thermography • The ability of facial thermography to detect disease in the internal carotid artery was evaluated. Unilateral forehead cooling of 0.7°C or greater was observed in 57% of 30 cases with angiographically proved stenosis. Two provocative tests, facial cooling and a head clamp, increased the sensitivity rate to 83%. The greatest overall sensitivi...

The purpose of this study was to devise and propose appropriate conditions for the photographing of thermal images in the oral cavity and to evaluate which thermography techniques can be applied to dentistry by evaluating the differences in temperature among oral tissues. Thermal images of oral cavities of 20 volunteers in normal oral condition were taken according to the guidelines of the Japa...

Non-destructive testing (NDT) by active infrared thermography requires of data processing techniques in order to: i. improve the thermal contrast between defective and non-defective areas, and ii. reduce the large quantity of images recorded during the inspection without losing relevant information. In this paper, the use of the skewness statistic parameter is proposed for the automatic process...

A total of 112 patients participated in a prospective study of after-exercise thermography as a screening method for predicting risk of postoperative deep venous thrombosis. The fibrinogen-uptake test was used to detect thrombosis after elective surgery. The incidence of the complication showed no significant difference between patients who had had positive and those who had had negative thermo...

We present a thermal conductivity measurement method for laser crystals based on thermal mapping of the crystal face by an infrared camera. Those measurements are performed under end-pumping of the laser crystal and during laser operation. The calculation of the fraction of pump power converted into heat is therefore simplified, and it is possible to link easily the temperature in the crystal t...
