A Novel Dual-Wavelength Method for Evaluating Temperature Effect in Fiber-Optic SPR Sensors

Abstract: The temperature effect is one of the critical factors to induce the resonance wavelength shift in fiber-optic surface plasmon resonance (SPR) sensors, which leads to the inaccuracy measurement of refractive index (RI) in practical applications. In this study, a novel dual-wavelength method is presented for fiber-optic SPR sensors to measure the changes of RI and temperature simultaneously in real time. A typical model of an SPR-based fiber optical sensor is constructed for theoretical analysis of temperature e… Show more

“…Therefore, to eliminate the error, temperature compensation is required. The temperature compensation technique can be carried out using two light sources with different wavelengths [36]. The usage of these two wavelengths contributes to a different output intensity, hence producing two sensor sensitivity values for both RI and temperature measurement.…”
