This paper introduces the concepts underpinning the realisation of micromachined resonator fibre optic sensors, discusses the achievements in prototype sensor systems realised to date and projects the future requirements which must be fulfilled before the technology can realise its full commercial potential. Measurements to 0.1% accuracy over very wide temperature ranges have been demonstrated to be feasible and applications in the difficult environments typified by aerospace, industrial, and automotive measurements and in chemical/biochemical systems are emerging. |
