Abstract

In this paper, Fiber Bragg grating sensor is studied and aline linear relationship between phase difference and strain is achieved. A Fabry-Perot interferometer is used to select a specific wavelength and a reference channel is introduced to compensate for random phase drifts, improve the sensitivity and the resolution.
