Paper Abstract

An acceleration sensor based on measurement of the reflection bandwidth of a single fiber Bragg grating (FBG) is presented. The FBG is glued in a slanted direction onto the lateral surface at the center of the beam. Two weights were fixed respectively on the upper and lower surfaces in the middle of the beam to sense the variation of the acceleration in the vertical direction. Preliminary experimental results indicate that when the acceleration was increased, the 3-dB bandwidth of the FBG responded linearly from zero to 8 g, with very low temperature dependence. The measurement sensitivity and resolution are 0.4 nm/g and 0.05 g, respectively.
