Electromagnetic feedback fiber optic accelerometer with wide bandwidth and high sensitivity
A closed-loop fiber optic accelerometer with wide bandwidth and high sensitivity based on electromagnetic feedback is proposed. Compared with the open-loop system, the bandwidth of 3 dB can be extended to about 210 Hz, which is increased by about 3.5 times, and the sensitivity is maintained at 72.97 dB re rad/g. At the same time, the sensor can also realize free bandwidth regulation to a certain extent to meet different application requirements.
