## Abstract A fiber optic distributed sensor, based on a Sagnac interferometer for determining the location of time‐varying disturbance, is presented in this paper. The proposed distributed sensor constitutes a Sagnac interferometer with an additional time delay fiber loop. Due to the time‐division
