The results of an investigation into the temporal response of fibre optic interfero-meters to heat pulses is presented. A rise time of < 2.5 x 10-4 s was determined where an electric arc was used to heat the fibre cladding. A response time of < 10-4 s was observed when an optical technique was used to directly heat the fibre core. These measurements were performed with a new remote optical configuration which could be used as a miniaturised sensing element. The feasibility of multiple measurement with this new fibre Fabry-Perot interferometer was studied, and two multiplexed sensing systems based on frequency division and coherence multiplexing are described.
