“…Various filters (in both time and frequency domains) and algorithms are used for minimizing noise, reducing blurring and edge preservation in thermal images [94]. Gulyaev et al suggested four fundamental numerical operations on the thermograms to increase accuracy of the data extracted from them [95]. These four operations are, (i) subtraction of background in each frame of interest, (ii) construction of temperature time profile at chosen point or regions, (iii) spatio-temporal projections of image sequences and (iv) calculation of time derivative of temperature data.…”

The primary objective of this study is the development of transparent thin film materials in the IR enabling strong infrared absorption of organic compounds in the vicinity of metal nanoparticles by the surface plasmon effect. For developing these optical micro-sensors, heterostructures combining gold nanoparticles and chalcogenide planar waveguides are fabricated and adequately characterized. Single As 2 S 3 and Ge 25 Sb 10 Se 65 amorphous chalcogenide thin films are prepared by radiofrequency magnetron sputtering. For the fabrication of gold nanoparticles on a chalcogenide planar waveguide, direct current sputtering is employed. Fabricated single layers or hetero-structures are characterized using various techniques to investigate the influence of deposition parameters. The nanoparticles of gold are functionalized by a self-assembled monolayer of 4-nitrothiophenol. Finally, the surface enhanced infrared absorption spectra of 4-nitrothiophenol self-assembled on fabricated Au/Ge-Sb-Se thin films hetero-structures are measured and analyzed. This optical component presents a ~24 enhancement factor for the detection of NO 2 symmetric stretching vibration band of 4-nitrothiophenol at 1336 cm −1 .

“…27 This process has been widely used to characterize temperature patterns of the body surface in the diagnosis of several diseases, and it could represent a valuable instrument for the analysis of biological tissues and physiological researches concerning the study of production and dissipation of heat during and after exercise. 7,8,27 Infrared thermography overcomes limitations observed in other methods that require physical contact to measure the temperature, 27,28 and it could offer indirect hemodynamic recruitment information of muscle masses during the process of exercise-related thermal adjustment. 17 The thermal changes that occurred in deep areas of the body are transferred to the superficial tissue by the blood circulation.…”

Exercise-Associated Thermographic Changes in Young and Elderly Subjects

This study aimed at evaluating the thermographic changes associated with localized exercise in young and elderly subjects. An exercise protocol using 1 kg load was applied during 3 min to the knee flexors of 14 elderly (67 +/- 5 years) and 15 young (23 +/- 2 years) healthy subjects. The posterior thigh's skin temperature of the exercised limb and contralateral limb were measured by infrared thermography on pre-exercise, immediately post-exercise, and during the 10-min period post-exercise. Difference (p < 0.01) between elderly and young subjects was observed on pre-exercise temperature. Although differences were not observed between pre-exercise and immediately post-exercise temperature in the exercised limb, thermographic profile displayed heat concentration in exercised areas for both groups. Temperature reduction was only observed for the young group on the 10-min post-exercise (p < 0.05) in the exercised limb (30.7 +/- 1.7 to 30.3 +/- 1.5 degrees C). In contrast, there was a temperature reduction post-exercise (p < 0.01) in the contralateral limb for both groups. These results present new evidences that elderly and young subjects display similar capacity of heat production; however, the elderly subjects presented a lower resting temperature and slower heat dissipation. This work contributes to improve the understanding about temperature changes in elderly subjects and may present implications to the sports and rehabilitation programs.
