Abstract
Optical Fibre Sensors (OFS) have many advantages over others type of sensors for measuring strain or micro-displacement. This paper introduces a new configuration of Bragg gratings within an optical fibre to improve strain measurement resolution and accuracy. We describe the geometry, together with the research direction currently being undertaken to produce a commercially viable micro-displacement sensor suitable for a number of architectural and engineering applications.
