“…Among them, infrared thermography is a tool that has shown its effectiveness in gaseous media [2,3] but cannot be used for a surface in a liquid environment. The measurement of the surface temperature by detection of a plasmon wave is a promising alternative [4,5,6,7] since the plasmon detects at a nanometric scale any change of the gaseous [8] or liquid medium [9,10] surrounding the surface. In addition, the surface plasmon resonance (SPR) measurement often reaches interesting sensitivities in terms of index variations [6].…”

The aim of this work is to measure the temperature variations by analyzing the plasmon signature on a metallic surface that is periodically structured and immersed in a liquid. A change in the temperature of the sample surface induces a modification of the local refractive index leading to a shift of the surface plasmon resonance (SPR) frequency due to the strong interaction between the evanescent electric field and the metallic surface. The experimental set-up used in this study to detect the refractive index changes is based on a metallic grating permitting a direct excitation of a plasmon wave, leading to a high sensibility, high-temperature range and contactless sensor within a very compact and simple device. The experimental set-up demonstrated that SPR could be used as a non-invasive, high-resolution temperature measurement method for metallic surfaces.
