Summary on Grant Application Form
This Faraday programme proposal addresses the area of opto-electronic instrumentation suitable for structural integrity monitoring applications on large engineering structures. It entails the design, development, evaluation and testing of rugged, portable fibre-optic strain monitoring instrumentation capable of muttipladng up to 500 straintlemperature sensors using a combined WDANTDM approach and be able to operate in harsh environments such as in the monitoring of remotely sited civil structures or in process control applications. Advanced instrumentaion developments will enhance the muRippladng capability while maintaining a high measurement performance. New fibre Bragg grating sensor elements will be developed to separate temperature and strain measurements while providing a high resolution (<1 ustrain), <0.1 C) without measureable cross-talc. The sensor system will undergo laboratory testing when attached to metal structures and be ceded into concrete beams for performance evaluation. A new polymer/concrete composite field trial road bridge structure at DERA will be instrumented as a field trial site using attachedlembedded fibre grating sensors and an on-line monitoring system will be developed to permit remote monitoring for data processing, fusion, reduction, analysis and display. In addition, the strain monitoring system will also be evaluated in an industrial laboratory environment at Corus Ltd, to assess its capability far monitoring the distortions in a steel making (BOS) refractory/steel plant for steel production optimisation.
