Application Notes

Title
Product Area
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: Measuring Strain with PEEK-Buffered Fiber Optic Sensor
  • ODiSI/HD-FOS
Short Summary
Discusses strain measurements obtained from PEEK fiber compared to polyimide fiber, when bonded onto a fiberglass coupon and loaded in tension.
Distributed Fiber Optic Sensing: Measuring Temperature on a Printed Circuit Board
  • ODiSI/HD-FOS
Short Summary
Demonstrates distributed temperature measurements to identify points of failure on a printed circuit board
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.
