Optical sensing system whereby the pulse repetition rate is effectively increased without having to reduce optical fibre sensor lengths or numbers by interleaving several interrogating signals. Many optical sensing systems include an interferometer comprising a plurality of contiguous optical fibre sensor lengths with partially reflecting discontinuities therebetween. An inherent problem with these systems is however that the number of sensors that can be configured is limited by the pulse repetition or sensor interrogation rate. |
