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.
