A Precision Fibre Optic CO2 Sensor – Mr James Barrington
James’s research is focussed on fabricating an optical fibre carbon dioxide sensor. Fibre optics possess compact dimensions and offer the ability for modulation in order to provide a sensing platform. Long period gratings are one form of modulation which are characterised by a series of a regular refractive index perturbations in the core of the optical fibre. These micro gratings allow the light transmitted in the core to interact with the surrounding environment thus providing sensing capabilities. Further precision can be achieved via the precise deposition of a carbon dioxide sensitive coating. It is anticipated that this device will be integrated with additional fibre sensors to provide a single multi-variant sensing platform.
James is located at Cranfield University in the Centre for Engineering Photonics, and is supervised by Prof Ralph Tatam and Dr Matthew Partridge.
