High-accuracy transient response fiber optic seismic accelerometer using a shock-absorbing ring as a mechanical antiresonator.

This study proposes a high-accuracy transient response fiber optic seismic accelerometer based on the resonance suppression mechanism. A shock-absorbing ring is embedded in the accelerometer structure, which acts as a mechanical antiresonator. The experimental results show that the sensitivity at the resonance frequency is suppressed by 21.
