Abstract
We propose a novel fiber Bragg grating (FBG) sensor demodulator using fiber birefringence. The demodulator is composed of a polarizing beam splitter (PBS), a polarization controller (PC), and a chirped fiber grating (CFG). In the sensor application of this paper, the CFG is used as a broadband reflection mirror. The experimental results showed that the demodulator has good performance for measuring static and dynamic strain
