Focus Sensors Limited

We will determine, though a short R&D project, with testing and demonstration at GCRE, whether we could reliably detect and locate line blockages resulting from rockfalls along with the more gradual appearance of track obstructions from earth and sand movement. We intend to use our system Indus connected to optical fibres often already installed next to t...

Fibre optic Acoustic Sensing (FOAS), also known as Distributed Acoustic Sensing (DAS) is a technology which converts optical fibres into distributed dynamic strain sensors. In rail, existing trackside fibre optic cables can be used to monitor infrastructure and trains, reporting data to within +/- 1m. Rail faces twin challenges of providing ever growing s...

Focus Sensors will build upon collaborative work undertaken with the rail industry in exploring where FOAS (fibre optic acoustic sensing) and our unique FOMS (fibre optic movement sensing) can enhance operational and management capabilities. Our technology leverages significant opportunity value from the presence of fibre optic cables running alongside ra...

When cable thefts occur the operation of the railway, often in nationally critical locations, can be brought to a standstill with significant impact on passengers and freight supply-chains. Under extreme industry and public pressure, Network Rail must delay scheduled activities and scramble teams to effect repairs and get critical railway operational syst...

Optical fibres are all around us, enabling long distance communications powering the internet, CCTV beside highways and signals on our railways. Distributed Acoustic Sensors (DAS) can connect to these fibres and, by measuring distributed dynamic strain, use them to infer the pattern of life near the fibre. DAS has possible use cases spanning multiple mark...
