Paper Abstract

A high sensitive fiber Bragg grating (FBG) acceleration sensor based on filtering demodulation is analyzed on sensitivity, resolution and temperature experiment. Sensitivity and resolution of FBG sensor lies on the structure of the sensor shell and the shape of the reflectivity spectrum of FBG. The temperature experiments of the FBG sensor show the work and storing temperature range of the sensor based on different preparing stress and packaging glue. Experiments on the detecting system's frequency character have been done. Results show that this acceleration sensor can detect the smallest acceleration of 1mm/s2 with a flat response from 5Hz to 40Hz.
