Fibre optic sensors - European networkEU project number: BRRT-CT98-5074The European market for fibre optic sensors has changed significantly since the last commercial market study in 1998. We have examined this evolution in terms of both sensor technological changes and market driven changes of the types of sensors and fields of applications.The basic conclusions of 1998 remain largely valid. The commercial introduction of fibre optic sensors in new markets is largely dictated by technological evolution. There is a lack of end-user awareness of what is commercially available or could be developed to answer unfulfilled market requirements.New end-user markets for fibre optic sensors have now become commercially significant, specially for distributed sensors embedded in large structures (buildings, dams, civil engineering structures).They are mainly based on Bragg grating technology. Biochemical fibre optic sensors, which have the potential of being minimally invasive and of requiring minute quantities of reactants, have also experienced significant developments. In the medical field, the type of applications for fibre sensors has shifted significantly since 1998.
The telecommunication industry continues to deeply influence the development of fibre optic sensor markets, but by now the influence works both ways.Components originally developed for fibre sensor needs, such as polarization controllers, are now successfully used to adjust telecom fibre transmission parameters which need to be controlled in high speed (10 and 40 GHz) optical networks.Consequently, some fiber optic sensor firms have largely moved over to the telecom field (a good example being the managing partner of FOSEN, Protodel International Ltd.!).The improved manufacturing techniques already developed, but mainly still under development, for telecom optical and fibre components, are likely to infiltrate the optical fiber sensor markets, as they offer the potential advantage of lower production costs.Since the extra price associated with fibre optic sensors has been a major barrier to the development of this industrial activity, these manufacturing techniques will improve the market potential of fibre optic sensors, so that some can realistically be considered for mass production after 2005. -

Συνοπτική Περιγραφή: Το έργο PoweR-LIBS στοχεύει στην ανάπτυξη καινοτόμου διαγνωστικής διαδικασίας για την ταχεία, εξ αποστάσεως και σε πραγματικό χρόνο αξιολόγηση της λειτουργικής κατάστασης συνθετικών μονωτήρων σε υπαίθριες γραμμές μεταφοράς ηλεκτρικής ενέργειας υψηλής τάσης. Η διαδικασία βασίζεται στην τεχνική της φασματοσκοπίας πλάσματος λέιζερ (LIBS – Laser-Induced Breakdown Spectroscopy) η οποία επιτρέπει το φυσικοχημικό χαρακτηρισμό της επιφάνειας συνθετικών μονωτήρων και συσχέτιση με τη λειτουργική τους κατάσταση. Στο πλαίσιο της προτεινόμενης έρευνας σχεδιάζεται η κατασκευή ολοκληρωμένου συστήματος που θα υλοποιεί, με βάση προηγμένη τεχνολογία εξ αποστάσεως ανάλυσης (remote sensing), την εφαρμογή της τεχνικής LIBS στο πεδίο (Remote-LIBS η R-LIBS) για το χαρακτηρισμό συνθετικών μονωτήρων χωρίς να απαιτείται απομάκρυνση αυτών από τις γραμμές μεταφοράς. Παράλληλα, θα αναπτυχθούν κατάλληλα υπολογιστικά εργαλεία, βασιζόμενα στη χρήση προηγμένων αλγορίθμων μηχανικής μάθησης και νευρωνικών δικτύων, για την επεξεργασία και αποτίμηση των φασματικών δεδομένων LIBS ώστε να επιτυγχάνεται αξιόπιστη κατηγοριοποίηση των μονωτήρων ως προς τα φυσικά, λειτουργικά χαρακτηριστικά τους. Η διαγνωστική διαδικασία περιλαμβάνει τη χρήση τηλεκατευθυνόμενου μη επανδρωμένου ιπταμένου οχήματος (Unmanned Aerial Vehicle, UAV) με σκοπό την οπτική επιθεώρηση των μονωτήρων για τον ακριβέστερο προσδιορισμό, στην επιφάνεια του κάθε μονωτήρα, της κατάλληλης περιοχής ανάλυσης με το σύστημα R-LIBS.

“Detection and Assessment of Seismic Damage in Reinforced Concrete, Transportation, Primary Tunnel Linings”Commission of the European Communities, DGX II, Project No. PL970848, Contract No. ENV4-CT97-0616
A new energy-based theory for seismic failure of reinforced concrete tunnel linings is proposed.The above theory has been confirmed by measurements on tunnel lining samples and will be applied to tunnels using an intelligent seismic monitoring system that is under development.This system will detect the deformations in reinforced concrete tunnels in real time and will assess the remaining capacity of the lining to dissipate energy and the degree of damage.It will thereby permit transportation officers to shut down a tunnel when conditions following severe earthquake activity warrant it.At the same time it will make it possible to avoid tunnel shutdown for inspection immediately after the earthquake when it is essential that transportation arteries remain open. -

Air conformal fibre optic ice detection systemGROWTH G4RD-CT-2001-00612Air Conformal fibre optic Ice Detection System (ACIDS) aims to develop and test a system in an icing tunnel which is capable of detecting the presence, thickness and type of ice accreted on the leading surfaces of rotary and fixed wing aircraft.The system will be capable of directly measuring ice formation on the leading surfaces, raise an alarm and automatically activate the de-icing cycle.The capabilities of the system is aimed at reducing engine power demand diverted to de-icing procedures in difficult flying conditions and hence substantially contribute to the safety of the aircraft.The project is bringing together European SMEs, major European helicopter and aircraft manufacturers and research institutes to work on a safety aspect of aviation which crosses national and company boundaries and addresses a growing and critical safety issue.

Project reference: IST-2001-38052Funded under:FP5-ISTAim is to develop intelligent interactive systems and multi-sensing technologies and their applications for health, mobility, security, comfort and environmental monitoring in the workplace, the car and at home.The emphasis is on bridging developments in micro-nano-sensors technology with research on innovative applications offering multi-sensorial and easy access to knowledge based services and applications at work, home, for people on the move and in relation to healthcare and environmental protection.Progress in lower cost sensor and actuator technologies, smart sensing systems, miniaturised networked modules, their integration with interfacing middleware and their applications play a major role in realising the Programme vision of an ambient intelligence landscape.The work focuses on:
- Optimisation or development of new leading edge applications making best use of improved sensor technologies, their networking and improved communication capabilities. This also includes developments in the light of research on inter-personal interactions and behavior.
- Customisation of the sensor, actuator, micro-system or miniaturisation technology to match the requirements of the envisaged applications as well as to fulfil their processing capability and networked functionality.
- Integration of sensors and actuators with intuitive interface middleware contributing to the use and development of intuitive systems e.g. interfaces capable of monitoring, understanding and interpreting presence, words, gestures and physiological parameters adaptive to user requirements and self-learning, as well as automatic personal identification and localisation for context sensitive tangible interfaces; and their use in related applications and services. In this perspective technology developments must be associated with social and behavioural research on personal interaction both with networked services and with other people through mediation.
