Distributed Fiber Optic Sensing: Measuring Strain Across Welds
  • ODiSI/HD-FOS
Short Summary
While traditional strain gages adhered to welds will average the strain across the gage area, HD-FOS sensing allows measurement of the strain profile across a weld with a very high spatial resolution. This engineering note demonstrates measurement of strain across the welding joints of a motorcycle handle bar instrumented with a fiber optic sensor.

Distributed Fiber Optic Sensing: Strain Measurements on Powder Coated Metal
  • ODiSI/HD-FOS
Short Summary
Powder coating is a method for electrostatically binding dry powder onto surfaces. While providing better protection for surfaces, this tough finish makes it difficult and time consuming to sand off when preparing the surface for strain sensor bonding. This engineering note shows that fiber optic sensors give accurate strain measurements even when bonded directly onto well adhered powder coated surface

Distributed fibre-optic temperature and strain measurement with extremely high spatial resolution.
  • ODiSI/HD-FOS
Short Summary
Scanning the Rayleigh scattering along a length of optical fibre enables a distributed sensor system where every point along the fibre acts as a sensor. This novel method allows quasi-continuous measurement of temperature and strain profiles over distances of up to 50 m with millimeter spatial resolution.
