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

, 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.

Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]

, 2006
Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.
