Paper Abstract

In this article, an embedded fiber Bragg grating temperature sensor system is proposed and researched. The demodulating system controls a Piezoelectric Ceramic (PZT) with sawteeth wave to scan the matching grating, then do photoelectric conversion using a detector, and use Digital Signal Processor (DSP) to find the max intensity. Meanwhile, use PZT drive voltage to control the central wavelength of sensor grating to demodulate. Then use the USB interface chip to realize the communication between DSP and the host computer, and send the collected data to the host computer. Finally, the real time temperature can be inquired and stored through the inquiring interface programmed by computer. The result demonstrates that this experimental system has the wave addressing range from 1540 to 1565 nm and the temperature resolution of 0.1°C.
