摘要：
A simple demodulation method for a fiber Bragg grating (FBG) temperature sensor is proposed and demonstrated, which uses a low cost commercial temperature-controlled wavelength scanning distributed-feedback (DFB) laser, a sensing FBG and a low-speed photodetector (PD). Relative high resolution is achieved by utilizing an FBG with enhanced temperature sensitivity design. Such a method may be suitable for applications requiring moderate resolution and low cost implementations.
