Abstract:Vector accelerometer has attracted much attention for its great application potential in underground seismic signal measurement. We propose and demonstrate a novel vector accelerometer based on three fiber Bragg gratings (FBGs) embedded in a silicone rubber compliant cylinder at 120° distributed uniformly. The accelerometer is capable of detecting the orientation of vibration with a range of 0° ~ 360° and the acceleration through monitoring the central wavelength shifts of three FBGs simultaneously. The experi… Show more
