Title (EN) SOLID-STATE NON-INVASIVE THERMAL CYCLING SPECTROMETER
(FR) SPECTROMETRE TRANSISTORISE A CYCLE THERMIQUE NON INVASIF
Abstract:
(EN) A solid-state device for the non-invasive generation and capture of thermal gradient spectra from sample tissues. The device includes an infrared transmissive layered window assembly (200) and elements for inducing a thermal gradient in sample tissues (350). Also provided is an infrared radiation detector (720) for detecting infrared emissions emanating from the tissue as the transient temperature gradient progesses into the sample tissues. The sensor provides output signals proportional to the detected infrared emissions. A data capture element is provided for the sampling of output signals received from the infrared radiation detector as the induced temperature gradient progresses into the sample tissue.
(FR) L'invention concerne un dispositif transistorisé pour la production et la saisie non invasive de spectres de gradient thermique à partir de tissus d'examen. Le dispositif comprend un ensemble fenêtre à couches de transmission infrarouge (200) et des éléments induisant un gradient thermique dans les tissus à examiner (350). L'invention concerne également un détecteur de rayonnement infrarouge (720) permettant de déceler les émissions infrarouge en provenance des tissus à mesure que le gradient de température transitoire progresse dans ces tissus. Le détecteur fournit des signaux de sortie proportionnels aux émissions infrarouge décelées. Il existe un élément de saisie de données pour l'échantillonnage des signaux de sortie reçus depuis le détecteur de rayonnement infrarouge, à mesure que le gradient de température induit progresse dans les tissus à examiner.
