| Description | Optical fibre are used to sense acoustic waves. Current commercial systems use cheap telecommunications fibre which have been optimised to transport data over large distances. These have a poor signal to noise ratio for sensing applications. From this award, we have developed and patented a new optical fibre for distributed acoustic sensing applications with a signal to noise ratio 100 times standard telecoms fibres. It also has better performance than any other commercial product on the market. |
| Exploitation Route | Andrei Donko is currently applying for further funding from the EPSRC Doctoral Prize and the Royal Academy of Engineering Enterprise Fellowship. The university is also exploring how to commercialise this work. |

| Description | This optical fibre can improve current commercial sensing systems performance. Distributed acoustic sensing has a wide range of applications: - for perimeter security in the defence sector; - downhole monitoring in oil and gas; - pipeline health monitoring; - power cable monitoring for offshore windfarms; - traffic flow monitoring; - structural health monitoring; - railway monitoring; |
