A multiplexed CW Brillouin system for precise interrogation of a sensor array made from short discrete sections of optical fibre [PDF]

open access: yes, 2008
A novel configuration for precise temperature sensing in an array of optical fibre sections is reported. The sections are chosen to have different Brillouin shifts, to enable separation of scattered light signals in the frequency domain, rather than the ...

Applications of polymer optical fibre grating sensors to condition monitoring of textiles [PDF]

open access: yes, 2009
Fibre Bragg gratings (FBGs) in polymer optical fibres (POFs) have been used to measure the strain in a woven textile. FBGs in both POFs and silica optical fibres were attached to a woven textile specimen, and their performance characterised.
