Multiplexed measurements of strain using short and long gauge length sensors
Multiplexed measurements of strain using short and long gauge length sensors
The paper discusses two complimentary optical fibre sensing techniques which have been researched for structural monitoring applications. The short-gauge-length sensor system is based on fibre gratings and has achieved a strain resolution below 1 microstrain. The long-gauge-length sensor system has achieved 100 micron spatial resolution using a new OTDR technique. Results are presented for surface-mounted and embedded sensors. Both sensors systems can be multiplexed to make more efficient use of the interrogating unit. Their system designs should be capable of being developed to meet real engineering applications.

Abstract
The paper discusses two complimentary optical fibre sensing techniques which have been researched for structural monitoring applications. The short-gauge-length sensor system is based on fibre gratings and has achieved a strain resolution below 1 microstrain. The long-gauge-length sensor system has achieved 100 micron spatial resolution using a new OTDR technique. Results are presented for surface-mounted and embedded sensors. Both sensors systems can be multiplexed to make more efficient use of the interrogating unit. Their system designs should be capable of being developed to meet real engineering applications.
