This paper presents a high-speed Raman temperature sensor that is highly compatible with current strain sensors. Challenging conventional assumptions, we found that at a communication wavelength of 193 THz, the optimal frequency for measuring Raman scattering power is not the typically dominant 206 THz, linked to stimulated Raman scattering, but rather around 195 THz, in proximity to the Rayleigh scattering peak. Our study demonstrates the effectiveness of real-time temperature sensing through the monitoring of power fluctuations in Raman scattering at this particular frequency. © 2024 Elsevier Science.

使用瑞利峰附近的拉曼光谱进行光纤温度传感

本文提出了一种与电流应变传感器高度兼容的高速拉曼温度传感器。挑战传统假设，我们发现在 193 THz 的通信波长下，测量拉曼散射功率的最佳频率不是通常占主导地位的 206 THz（与受激拉曼散射相关），而是在 195 THz 左右，接近瑞利散射峰值。我们的研究通过监测该特定频率下拉曼散射的功率波动证明了实时温度传感的有效性。 © 2024 爱思唯尔科学。版权所有。
