摘要：
We present a method to simultaneously measure the temperature and electric current, which can be applied for the all-fiber optic current sensor (AFOCS) temperature compensation. The Faraday rotation mirror is introduced as the temperature sensing unit based on the all-fiber dual-modulation optic current sensor. The temperature and electric current could be distinguished by the sequence of pulse light received by the photodetector. The working principle of temperature and electric current sensing are analyzed by modeling and simulation. The experiments are designed to confirm the temperature compensation scheme. The relative error of AFOCS decreases from 14% to 2% by temperature compensation, which meets the requirements of micro-current fiber sensing.
