Optical Backscatter Reflectometer™: OBR 4600
Adding Luna Technologies' Distributed Temperature and Strain Sensing Software upgrade to the Optical Backscatter Reflectometer™ (OBR) transforms standard telecom-grade fiber into a high spatial-resolution strain and temperature sensor. The ability to use standard telecom-grade fiber eliminates the need for expensive specialty fibers usually necessary for precise measurements.

Using standard telecom-grade fiber, Luna's OBR monitors changes in the amplitude and phase of the light that is naturally back-reflected from standard optical fiber. Thus, Fiber Bragg Gratings are not required in the sensing fiber – the fiber itself is the sensor.

Benefits of combining Distributed Temperature and Strain Sensing Software with the Optical Backscatter Reflectometer™ (OBR):

  • Use standard telecom-grade fiber. No more expensive specialty fibers needed for measurements.
  • Highly distributed fiber sensing for strain and temperature
  • Very high spatial resolution: down to 2 mm
  • Centimeter resolution up to 70 meters
  • /- 0.1°C , /- 1µ strain resolution at 1 cm
  • High speed – five second acquisition times at high resolution

Applications:

Short range communications networks (local intranet, fiber to the home, shipboard and aircraft data bus):

  • Find high operational temperatures that degrade lifetime or performance of components
  • Determine if strain induced during installation exceeds safe threshold
  • Look for long-term strain concentrations that threaten fiber integrity

Structural monitoring for naval, aerospace and civil structures:

  • Conformal deformation and shape sensing
  • Composite damage assessment
  • Bonded joint integrity monitoring

Temperature profile monitoring:

  • Fuel cells
  • Concrete cure temperature monitoring in large structures
  • Industrial chemical process monitoring

Pipeline shift and leak detection
Electrical power line sag and temperature monitoring
