Title (EN) INFRARED IMAGE SENSOR
(FR) CAPTEUR D'IMAGE INFRAROUGE
Abstract:
(EN) The invention relates to an infrared image sensor comprising, on a base (10), a plurality of first pixels (32) and a plurality of second pixels (34) intended to capture infrared radiation emitted by an element in a scene, each pixel comprising a bolometric membrane (14) suspended above a reflector (12) covering the base, the reflector of each first pixel being covered with a first dielectric layer (40) and the reflector of each second pixel being covered with a second dielectric layer (42) different from the first dielectric layer by virtue of the optical properties thereof.
(FR) L'invention concerne un capteur d'image infrarouge, comprenant sur un support (10) une pluralité de premiers pixels (32) et une pluralité de deuxièmes pixels (34) destinés à capter un rayonnement infrarouge émis par un élément d'une scène, chaque pixel comprenant une membrane bolométrique (14) suspendue au-dessus d'un réflecteur (12) recouvrant le support, le réflecteur de chaque premier pixel étant recouvert d'une première couche diélectrique (40), et le réflecteur de chaque deuxième pixel étant recouvert d'une deuxième couche diélectrique (42) différente de la première couche diélectrique par ses propriétés optiques.
