Abstract

A facilitated fiber Bragg grating detection system for detecting temperature is presented. The scheme uses a processing fiber Bragg grating that is stuck on a cantilever beam and is identical to one used as a sensor to demodulate the temperature signal. A step motor that is controlled by PLC (Programmable Logic Controller) stretches the cantilever beam periodically, and the system of two gratings produces a carrier at this frequency with its phase modulated by the temperature signal applied to the sensing grating. The temperature signal, which is demodulated by this system, is transmitted to PC then processed and displayed in PC. This system’s configuration is simple, sensitivity is high, and cost is low.
