Abstract :
We describe some recently developed fibre grating sensing devices (Bragg and long-period types) and applications with emphasis on simultaneous measurement of multiple measurands using combinational grating structures, and the realisation of ultra-high sensitivity sensors utilising the quadratic dispersion of long-period grating structure.
