  • Device for revealing spatial variations in the polarisation of electromagnetic radiation
    Patent number: 11959953
    Abstract: A device is suitable for revealing spatial variations in polarization of an electromagnetic radiation, in a form of localized temperature variations. The device includes a surface of a carrier which is electrically and thermally insulating, and includes an array of patterns which each consist of at least one rectilinear segment of a sensitive material, of which the orientation is variable within each pattern or between neighboring patterns. Such device may be used with a thermal camera to reveal, in infrared images, temperature variations which are localized at segments not perpendicular to a local direction of linear polarization of the radiation.
    Type: Grant

  • Sensitive component for device for measuring electromagnetic field by thermofluorescence, corresponding measurement and manufacturing methods
    Patent number: 11112443
    Abstract: A component sensitive to an electromagnetic field, which includes a first absorbent material, able to partially absorb energy of a given electromagnetic field and converting the absorbed energy into heat. The sensitive component includes a second fluorescent and thermosensitive material, placed in contact with the first material in order to store the heat converted by the first material. The second material is able to re-emit, under the action of a predetermined excitation light, a light by fluorescence with light intensity dependent on the stored heat.
