Title
(EN) SUBSTRATE TEMPERATURE MEASUREMENT BY INFRARED SPECTROSCOPY
(FR) MESURE DE LA TEMPERATURE D'UN SUBSTRAT PAR SPECTROSCOPIE A INFRAROUGE
Abstract
(EN)
The temperature of an infrared radiation scattering medium which contains water, for example, biological tissue and paper, cement and clay substrates, is determined by exposing the medium to infrared radiation, measuring the reflected radiation scattered by the medium, comparing the reflected radiation with calibrated values, and evaluating the temperature of the medium from the comparison; the technique provides a means of non-invasive determination of temperature in biological tissue which has utility in medical diagnosis.
(FR)
On détermine la température d'un milieu de diffusion de rayonnement infrarouge contenant de l'eau, par exemple, des tissus biologiques et des substrats en papier, ciment et argile, par exposition du milieu à un rayonnement infrarouge, mesure du rayonnement réféchi diffusé par le milieu, comparaison du rayonnement réfléchi à des valeurs étalonnées, et évaluation de la température du milieu à partir de la comparaison; la technique offre un moyen de détermination non invasif de la température de tissus biologiques présentant une utilité dans le diagnostic médical.
