The signal-to-noise ratio (SNR) of fiber-optic gyroscopes (FOGs) is directly impacted by the optical power coupled to the interferometric circuit. The optical intensity noise produced by the optical broadband source becomes the major component of the

This paper presents experimental results comparing the susceptibility of two different optical fiber current sensors to environmental acoustic vibrations. Of the two sensors that are tested, one employs a uni-directional current detection scheme, and

The authors demonstrate for the first time a near shot noise limited in-line Sagnac interferometer current sensor. It is shown to have a number of advantages over the optical current sensors based on polarimetric Faraday and Faraday/Sagnac loop inter

We show the Sagnac interferometer as a two-parameter sensing device where nonreciprocal and reciprocal effects can be independently and simultaneously monitored. Phase shifts induced by nonreciprocal effects affect differently the counterpropagating

We have employed a Sagnac interferometer to measure small optical phase shifts induced by the Fresnel drag effect on moving media. The system detects volumetric flow rates of water as slow as 43 µL/min while maintaining a small pressure drop across
