Interrogation of birefringent fiber sensors using fiber gyroscope technology

A novel fiber interferometer, adapted from a Sagnac-type interferometer with non-reciprocal phase modulation, is used to measure the differential optical phase shift in birefringent fiber sensors. The interferometer is applied to voltage sensing.
