1. Infrared radiation source (100) comprising a membrane, the membrane comprising:

  • an emissive layer (130), comprising an emissive surface (131), and intended to emit infrared radiation from said emissive surface (131) when it is heated,a plurality of adaptation means (121a, 121b, 121c, 121d), each adaptation means (121a, 121b, 121c, 121d) facing a different section of the emissive surface (131) called the emissive section (132a, 132b, 132c, 132d), and with which it forms an emissive assembly 134a, 134b, 134c, 134d) configured to emit infrared radiation with a smaller spectral range than the infrared radiation that can be emitted by the emissive section (132a, 132b, 132c, 132d) alone, and centred around a central wavelength, said central wavelength being different from one emissive assembly to the other,a plurality of means (140a, 140b) of heating the emissive layer (130), the heating means (140a, 140b) being arranged so as to impose a variable temperature gradient on the emissive layer so as to vary the relative distributions of infrared radiation wavelengths effectively emitted by each of the emissive assemblies (134a, 134b, 134c, 134d).
