Abstract
The structure and performance of an all polarization-maintaining fiber optic accelerometer is described in this paper. The all polarization-maintaining fiber optic interferometer structure can avoid instability of polarization. With phase generated carrier technology, the signal fading caused by random phase-shift in the interferometer is eliminated. The experimental results show that the stable acceleration signal is attained and the measured resonance frequency of the system is 950 Hz. The on-axis acceleration sensitivity is 656 rad/g. The minimum measurable acceleration reaches 15ng/√Hz . The measured frequency response curve is in good agreement with that of theoretical analysis. The experimental results indicate that the accelerometer is useful for research and industrial applications.
