Abstract

A metal packed fiber Bragg gratings accelerometer has been proposed. Copper was adopted to cover the surface of optical fiber by magnetron sputtering and electroplating technology, and then tin soldering was used to fix the metalized fiber on mass and foundation. Because of copper coating and soldering, the elastic coefficient and ductility of FBGs have been increased, and the problems of aging and creep arising from polymer or adhesive packaged have been avoided. Experiment result demonstrated that the accelerometer possess of a resonant frequency of 2800Hz, a wide linear measurement range from 0.5g to 5.3g and a sensitivity of 84mv/g.
