Abstract
A method and system for visualizing infrared radiation emitted by a source, the visualizing system including a substrate, at least one solid temperature-sensitive layer containing thermochromic pigments having at least one transition temperature TH associated with a visible color change, and at least one intermediate layer placed between the substrate and the solid layer containing thermochromic pigments; the substrate, the at least one intermediate layer and the solid temperature-sensitive layer containing thermochromic pigments forming a multilayer suitable for absorbing infrared electromagnetic radiation and for inducing a local temperature increase dT; and the at least one intermediate layer being suitable for transferring, by thermal conduction, the local temperature increase dT to a region of the solid temperature-sensitive layer, so as to induce a local change in the visible color of the solid temperature-sensitive layer of thermochromic pigments.
