Optical fiber sensors have been extensively studied owing to their advantages such as immunity to electromagnetic noise, light weight, etc. Among various fiber sensors, here we focus on the method of measuring the temperature near the tip of the fiber. Conventionally, some complicated processing around the vicinity of the fiber tip was required to fabricate fiber-optic temperature sensing probes, which leads to high implementation cost. In this work, we propose a new method based on our original distributed sensing technique called low-coherence Brillouin optical correlation-domain reflectometry (BOCDR). In low-coherence BOCDR, a noise-modulated light source is used to achieve high spatial resolution determined by a principle different from that of standard BOCDR. We show that our method can measure the local temperature near the fiber tip using a simple experimental setup, which does not required any special processing of the sensing fiber and effective in cost. |
