Research output: Contribution to journalArticlepeer-review


An optical fibre sensor system for humidity and temperature, comprising two Bragg gratings recorded in silica and polymer fibre, has been characterised. The response of this system is very well conditioned (2-norm condition number = 8.8) and consequently uncertainties in wavelength measurement do not lead to large errors in the recovered humidity and temperature.
