Abstract
An image sensor including includes on a support a plurality of first pixels and a plurality of second pixels intended to detect an infrared radiation emitted by an element of a scene. Each of the pixels includes a bolometric membrane suspended above a reflector covering the support, wherein the reflector of each of the first pixels is covered with a first dielectric layer, and the reflector of each of the second pixels is covered with a second dielectric layer differing from the first dielectric layer by its optical properties.
