Current Research
Robert's research is focussed on fibre optic sensor [FOS] technology and its application in the
engineering environment, essentially measuring with light. Optical sensing is using the wavelength of
light as a ruler. Fibre optic sensing offers a near unique ability to carry out distributed or quasi
distributed sensing over long lengths (many kilometres) of fibre with high spatial resolution. FOS has a
high immunity to electro magnetic fields and can operate in harsh and hostile environments including
nuclear environments. In-fibre grating sensors (Fibre Bragg gratings and Long period gratings) can be
ideal sensor components for a wide range of physical, mechanical and chemical sensor applications
with. The ability to multiplex many sensors along a single length of fibre not only greatly simplifies
installation in complex environments but also allows spatial discrimination and the wavelength
encoded nature of the signal makes these sensors ideally suited to harsh environments. We have
developed a wide range of sensor solutions and interrogation techniques for barometric pressure,
location, shape, vibration and distance sensing in complex engineering environments. More recently
our research concentrated on the application of Rayleigh back scatter technology for distributed sensing
with high spatial and measurand resolution. This research is aimed at ground breaking new
developments in distributed shape and load monitoring in engineering components ranging from high
resolution load mats to large scale silo structures. Rapid Manufacturing technology [RM] is quickly
gaining a significant foot hold in the production of highly complex / high value / small volume
components. We investigate the ability to integrate secondary components into the RM build process,
including fibre optic sensor elements. These elements would enable in-situ monitoring of components
with minimal interference on the design and manufacturing process paving the way towards smart
materials.
