| 摘 要： | 激光脉冲进入光纤中,与光纤分子相互作用,产生Raman散射和Raylei曲散射。由于Raman散射具有温度效应,其散射光强度受温度调制,可作为温度信息的载体,用于温度解调及测温系统设计。本文提出了可行的温度解调方法及理论推导,并推导出单通道和双通道条件下的测温关系,设计出两种条件下的传感器系统。

| Abstract: | When laser pulse enters into optical fiber, laser photon processes with optical fiber molecule, Raman scattering and Rayleigh scattering will be produced. In virtue of domino offect of Raman scattering, it's scattering light intensity is modulated by temperature, so Raman scattering light can be considered carrier of temperature information and used for temperature demodulation and system of measure temperature. Manifold methods of temperature demodulation were introduced, equations of measure temperature in single channel or double channels were demonstrated. |
