Paper Abstract

We determine the noise coefficients of a Fiber Bragg Grating Accelerometer (FBGA) at static operation using Allan Variance Method. We describe the mechanical structure of the FBGA, as well as the embedded optical and electronic circuits used to acquire the experimental data. Comparing the Root Allan Variance Plot of our topology with two MEMS accelerometers plots, one from a theoretical article and another from a commercial datasheet, we observe that FBGA results show a relative low noise profile.
