Abstract

In this paper, a review is given on the principles of optical fiber Bragg grating (FBG) sensors and their applications a strain sensors. Since the discovery of photosensitivity in optical fibers there has been great interest in the fabrication of Fiber Bragg Gratings within the core of a fiber. The ability to inscribe Bragg gratings in these photosensitive fibers has revolutionized the field of optical fiber based sensor technology. This work reviews the achievements about the FBG as a strain sensor and describes the potential applications of these sensors. The present paper discusses some of the parameters of gratings, which are important for sensor's constructions. These sensors are constructed on the basis of elasto-optic effects where the deformation is coded in wavelength.
