| Abstract: | In order to provide a high accuracy three-component accelerometer for seismic exploration in the high electro-magnetic area, a novel three-component photoelastic fiber optic accelerometer with good linearity and high transverse resonance is designed. Based on the photoelastic effect, three-axis photoelastic sensing systems are designed to measure the three-orthogonal components of acceleration. Dual-spring system in the accelerometer increases the linearity and transverse resonance of the accelerometer. The main design parameters of the accelerometer are as following: natural frequency: 3500Hz; transverse sensitivity ratio: 0.11%; on-axis phase detection sensitivity: 3.7×10 -3 (rad/m/s2 ). |
| Keywords: | three-component photoelastic effect accelerometer transverse resonance sensitivity |
