DESCRIPTION

  • Fiber laser system based on Fabry-Perot interferometry
  • The system is based on dual modulation:
    - An optical fiber combined with a collimator forming the detection module
    - An electronic part forming the treatment module
  • This system architecture enables to:
    - Identify target movements’ direction
    - Detect very slight movements
  • Due to the use of optic fiber:
    - Disturbance tolerance of the system
    - No embedded electronics within the measurement zone
 

APPLICATIONS

  • Applicable in harsh & hard to access environments
  • Monitoring:
    - Structure
    - Seismic
    - Geophysics
  • Multi-points measurement
