| Abstract: | To avoid the interference of electromagnetism to magnetoelectric sensors, a mathematical model between acceleration and wavelength was proposed with the analysis of fiber Bragg grating acceleration sensors' mechanical model, and then a low frequency fiber Bragg grating acceleration sensor was designed. With the experiment, the frequency range of amplitude is 45 Hz and the cross-axis disturbance is 40 dB, which means that the sensor can be used in practice. |
