Patent ID: 10641702

Abstract:
A source (100) that includes a membrane, where the membrane includes: an emissive layer (130) including an emissive surface (131); an adaptor (121a, 121b, 121c, 121d), each adaptor (121a, 121b, 121c, 121d) facing a different section of the emissive section (131), called the emissive section (132a, 132b, 132c, 132d), and with which it forms an emissive assembly (134a, 134b, 134c, 134d) adapted to reduce the spectral extent of infrared radiation emitted by the emissive section; and a plurality of heaters (140a, 140b) for heating the emissive layer (130), the heaters (140a, 140b) being arranged so as to impose different relative temperature variations in different emissive sections (132a, 132b, 132c, 132d).
