Abstract. Fibre optic (FO) distributed strain sensing technology has introduced a significant new capability for structural health monitoring (SHM). FO sensing (FOS) offers a simpler installation process with improved resistance to corrosion and electromagnetic interference compared to traditional electrical resistance foil strain gauges (FSGs) which unlike FOS is limited to single point measurements. Previous FO distributed strain measurement studies at the Defence Science and Technology Group showed good correlation between strain measurements derived from a proprietary continuous fibre grating system and FSGs. This paper compares a commercially available, non-proprietary FO sensing system and digital image correlation (DIC) against industry standard FSGs and finite element analysis (FEA) predictions.
