What is a Fiber Bragg Grating? Fiber Core L Period, It Ii λ Λ Fiber Bragg Gratings Transmitted Signal λb λ Ir Reflected Signal λb Measurand Induced Shift λ

Phase masks , tooling to make fiber Bragg gratings

Phase Mask technology

Benefits • FBG is small in size and light in weight • Long operating life, immune to radiation • Ideal for remote and distributed sensing • FBG sensor is passive, draws 0 power • Immune to RFI and EMI • Can work in hostile environment, like extreme temperature

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

PD Emulator

It features high signal to noise ratio

This signal to noise is generated by the optical gain of the special fiber cavity

Measures broad range of vibration non contact

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)

The spectrum of a single sensing element.

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
