摘要

A dual-frequency distributed Bragg reflector (DBR) fiber laser based sensor is demonstrated for low-frequency vibration measurement through the Doppler effect.The response of the proposed sensor is quite linear and is much higher than that of a conventional accelerometer.The proposed sensor can work down to 1 Hz with high sensitivity.Therefore,the proposed sensor is very efficient in low-frequency vibration measurement.
