Abstract
A strategy for suppressing the perturbations of an intensity-based optical fibre sensor is presented by introducing an adaptive noise cancelling method. The time-varying offset between the sensing fibre arm and the reference fibre arm can be significantly reduced by the proposed strategy compared to direct subtraction. Experimental results are provided to demonstrate the performance of the perturbation suppression.
