• Abstract: A temperature sensing measurement scheme based on fiber-coupled light- powered conversion probe is proposed. The sensing probe is powered by a 20 mW semiconductor laser with stable fiber transmission, which improves the coupling efficiency of the light source and the fiber. The optical drive and detection signals are isolated by optical fiber. The sensor probe has the characteristics of high voltage resistance and electromagnetic interference resistance, and the power consumption is less than 2.0 mW. Experiments have verified the feasibility of measuring temperature, high current and other parameters with this method. The developed instrument has higher detection sensitivity and accuracy. 提出一种基于光纤耦合光推动式转换探头的温度传感测量方案。传感 探头采用光纤传输稳定的 20 mW 半导体激光器供电，提高了光源和光纤耦合效 率。光推动和检测信号均采用光纤隔离，传感探头具有耐高压，抗电磁干扰能 力特性，功耗小于 2.0 mW。实验验证了用该方法实现的温度、高电流等参数测 量的可行性，研制的仪器具有较高的检测灵敏度和精度。
