Research abstract
"Blue Road Research intends to extend the use of both high reflectivity, wavelength multiplexed grating sensors and low reflectivity, interferometrically multiplexed grating sensors to measure multi-dimensional strain fields in bonded joints in aerospacestructures, and use this strain field information to monitor structural integrity over the vehicle lifetime. In addition, Blue Road Research in cooperation with OFT Associates will create a physical demonstration of a new strain demodulation techniquethat would allow truly distributed, high resolution (sub-mm), high definition multi-axis strain measurements ideally suited to monitor localized crack propagation in composite structures."
