Strain Sensing

 Luna’s fiber optic sensing solutions deliver strain measurements that go beyond what’s possible with traditional strain gages.Distributed strain measurements

Three types of fiber optic strain sensors offer a wide range of strain measurement capabilities without sacrificing precision and sensitivity.

High-Definition Distributed Strain Sensing 

High-definition strain sensing based on the Rayleigh backscatter delivers a virtually continuous line of strain measurements with sub-millimeter spatial resolution, employing very small lightweight optical fiber sensors that can be easily embedded or installed in challenging locations.

  • Map strain profiles with high spatial resolution (down to 0.65 mm)
  • Sensors available in lengths from 1 m to 100 m
  • Small, lightweight and flexible fiber sensors

High-Speed Multipoint Strain Sensing

Strain sensors based on fiber Bragg gratings (FBGs) deliver accurate and stable strain measurements that can be multiplexed and distributed over a large area using a single optical fiber sensor network.  FBG Strain Sensor

  • Combine multiple point sensors on singe fiber channel
  • Up to 16 channels on interrogator system
  • Static and dynamic measurements 
  • Discrete FBG strain sensors packaged for accuracy, repeatability and ease of installation

Long-Range Distributed Sensing with OptaSense

Able to measure distributed strain, temperature and acoustic phenomena over very long optical fibers up to 100 km in length, the OptsSense line of DAS interrogators are ideal for monitoring pipelines, highways, railways, power lines, borders and perimeters.  

  • Long distributed sensors up to 100 km in lengthOptaSense
  • Distributed strain with 1 m resolution

High-Definition Distributed Fiber Optic Sensing

Unlike conventional strain gauges that only measure strain at a discrete point, Luna's high definition fiber optic strain gauges provide continuous, high-resolution (less than 1 mm) measurements of strain along the entire length of the sensor (up to 50m).
