【Abstract】 A new approach for displacement sensing based on chirp effect of fiber Bragg grating under strain gradient is proposed and demonstrated in this paper. The theoretical analysis and the experimental fitting curve are given. The researches indicate that the system has advantages of simple configuration, good noise immunity, and good linearity (about 0.9992).更多还原
