CA 2444490

At least one infrared sensor or a one dimensional sensor array are aimed at a target. A movable mirror scans the target of interest to provide a thermal "image" of the target area. Processing electronics detect the hottest spot of the target as indicated by output signals to directly indicate or estimate a temperature. Preferably, output can be utilized to determine the core temperature of a patient by examination of a target such as the tympanic membrane which is interconnected to the hypothalamus.

L'invention concerne au moins un capteur infrarouge ou un réseau de capteurs unidimensionnel destinés à une cible. Un miroir mobile balaie la cible d'intérêt en vue de fournir une "image" thermique de la zone cible. Des composants électroniques de traitement détectent le point le plus chaud de la cible sur la base de signaux de sortie de façon à estimer ou indiquer directement une température. De préférence, la sortie peut être utilisée pour déterminer la température interne d'un patient par examen d'une cible telle que la membrane du tympan, laquelle est reliée à l'hypothalamus.
