Intra-grating sensing with a chirped fibre Bragg grating employing an integration method Open
A method to recover arbitrary temperature profiles along a chirped fibre Bragg grating sensor is presented. We demonstrate a nonlinear lookup table method to recover the shape, width and position of a disturbance in temperature after compe…

Spectral analysis for broadband fluorescence: temperature sensing with the YAG:Ce phosphor as an example Open
Temperature-dependent fluorescence of YAG:Ce was studied as an example of a spectral characterization method.According to the steady-state emission at various temperatures, four types of temperature sensing functions were retrieved using b…

Stress- and Temperature-Dependent Wideband Fluorescence of a Phosphor Composite for Sensing Applications Open
As both stress and temperature can alter the lattice of a solid phosphor in a similar way, the dopant rare-earth ion may be used as a probe for either parameter using the same sensing mechanism. Here, a wideband phosphor, YAG:Ce is used as…

Intrinsic determination of pH using a barycentre algorithm to characterise fluorescence from an optical fibre sensor Open
An algorithm to determine the barycentre of the signal received from a fluorescence-based fibre optic sensor probe has been implemented for the intrinsic characterisation of the fluorescence spectra of a pH sensor using coumarin dyes.
