A DBR fiber laser sensor is a Vibrofibre with Active fiber cavity
Top view of the designed PD sensor actual unit will have both an input and an output Stress relief Optic fiber
Dimensions are in mms connectors will come out of both sides and the length will be shorter
This signal to noise is generated by the optical gain of the special fiber cavity

Low frequency vibration 时域 施加 检测 输出电压 时间
Distributed temperature and low frequency vibration measurement • Use of FDM technology • The interrogation unit is a separate subsystem • Sensing elements consist of an FBG array each element has an identical center wavelength • The array can be up to 200 elements each
Each sensor box contains 2 fiber coils Vibration Fiber loops FBG, l Distributed Vibro Sensor Box D > 5 m Vibro Sensor Box Distributed Vibro Sensor Array
FDM Technology: Generating a Chirped waveform by scanning the laser current
The various frequencies act as labels on all the FBG sensors
The sensor array (sensor spacing does not need to be regular)
Design of the broad band triangular grating for demodulation
Shift in center wavelength due to vibration and temperature, vibrations will be periodic
Output voltage amplitude change can be related to temperature or strain
