Title
(EN) SENSOR AND METHOD FOR DISCRIMINATING BETWEEN WAVELENGTH REGIONS USING THE SENSOR
(FR) CAPTEUR ET PROCÉDÉ DE DISCRIMINATION ENTRE DES RÉGIONS DE LONGUEUR D'ONDE À L'AIDE DU CAPTEUR
Abstract
(EN)
A sensor for discriminating between wavelength regions in an electromagnetic spectrum is disclosed. The sensor comprising a substrate, a sensing element supported on a surface of the substrate, and at least one pair of terminal electrodes disposed on the substrate surface in mutually spaced apart and opposing relation, and in electrical contact with the sensing element, wherein the sensing element is responsive to electromagnetic radiation to yield a change in photocurrent measured between the terminal electrodes as a function of an intensity of the electromagnetic radiation impinging thereon, wherein a positive dependency on the intensity corresponds to a first wavelength region and a negative dependency on the intensity corresponds to a second wavelength region.

L'invention concerne un capteur permettant de discriminer entre des régions de longueur d'onde dans un spectre électromagnétique. Le capteur comprend un substrat, un élément de détection supporté sur une surface du substrat, et au moins une paire d'électrodes de borne disposées sur la surface du substrat dans une relation mutuellement espacée et opposée, et en contact électrique avec l'élément de détection, l'élément de détection étant sensible à un rayonnement électromagnétique pour produire un changement de courant photoélectrique mesuré entre les électrodes de borne en fonction d'une intensité du rayonnement électromagnétique incident sur celui-ci, une dépendance positive sur l'intensité correspondant à une première région de longueur d'onde et une dépendance négative sur l'intensité correspondant à une seconde région de longueur d'onde.
