how to make distributed fiber-optic sensors for vibration detection?


Overview

The Distributed Fiber Optic Vibration Sensing System (DVS) is an optical instrument that uses an optical fiber as a sensor for vibration sensing. The system uses a single optical fiber to simultaneously monitor vibration and transmit signals. Distributed fiber optic sensing technology is an emerging sensing technology. Temperature, strain, and vibration (sound) information can be obtained in real time at any point on the tens of kilometers-long detection fiber optic cable.It can be applied to the perimeter security of important buildings, long-distance oil and gas pipeline monitoring, oil and gas resources, intelligent transportation and other fields.

How to implement a distributed fiber optic vibration sensing system

DVS system includes hardware components and software, we focus on providing DVS hardware components, the software program needs to be developed by you.

DVS Hardware Components

We offer integrated DVS modules for users who focus on software algorithms, and we also offer lasers, balanced photodetectors and other related devices for customers who want to develop their own DVS hardware. You can choose to buy them according to your needs.

2 Ways to Make Your Distributed Fiber Optic Vibration Sensing System

Option 1: Using integrated modules

Applicable users: Users focus on business domain knowledge, do signal data identification analysis, algorithms, don't want to spend too much energy on hardware development, want to realize distributed fiber optic vibration system at low cost for enterprise/university research labs, team with software programming capability.

Build steps.

  • Buy distributed fiber optic vibration sensing system DVS/DAS integrated module
  • Buy high-speed DAQ cards for distributed fiber optic vibration sensing systems
  • Buy an IPC and power supply (you can use your own computer instead), which needs to support PCIE interface.
  • Connect the sensing fiber optic cable and write software to do data processing on the computer according to your business area

Option 2: Self-developed distributed fiber optic vibration system using lasers and other components

Applicable users: university laboratories, graduate students of scientific research institutions and R&D departments of enterprises that are good at hardware, optical devices, FPGAs, etc., familiar with fiber optic sensing principles, familiar with DVS/DAS optical paths, and want to implement distributed fiber optic vibration systems independently.

Build steps.

  • Buy optical devices such as narrow linewidth lasers, EDFA, AOM, Raman amplifiers, photodetectors, etc.
  • Buy high-speed DAQ cards for distributed fiber optic vibration sensing systems
  • Device connection, debugging, and solving various problems encountered during debugging
  • Acquire data and do signal demodulation processing to implement your own software program.
