## Abstract A fiber optic distributed sensor, based on a Sagnac interferometer for determining the location of timeβvarying disturbance, is presented in this paper. The proposed distributed sensor constitutes a Sagnac interferometer with an additional time delay fiber loop. Due to the timeβdivision
Currently There Is Considerable Interest In The Application Of Optical Meth Ods For The Measurement Of Absolute Rotation. Active Approaches, So-called Ring Laser Gyros, Have Been Under Serious Development For At Least 15 Years. More Recently, Passive Approaches Using Ring Resonators Or Multi Turn Fi
