Abstract
Fiber Bragg grating is simple, intrinsic sensing elements which can be photo-inscribed into a silica fiber. It has many advantages and be useful for a variety of application. In this paper, we reported the experimental results of measuring the three-dimensional thermal expansion coefficients of Beryllium by using fiber Bragg grating (FBG) sensors within a large temperature range between -50°C and +150°C. Three FBG sensors were bonded on the surface of the material in the directions of x, y, z to measure the three-dimensional thermal expansion coefficients and a reference FBG sensor was used to compensate the temperature variation. The experimental results show that it can be used in harsh environment.
