Abstract: A new scheme capable of suppressing polarisation sensitivity in the Brillouin optical time domain analysis distributed sensing system is demonstrated. The polarisation-induced signal fluctuation is suppressed from >±300ε (which causes measurement to fail) to ±50ε by introducing a cost-effective polarisation diversity scheme on the pump light. Stable distributed strain measurement along a 1.2km singlemode fibre is achieved. This scheme needs no active component and the strain measurement time is only 3s. © The Institution of Engineering and Technology.
