Paper Abstract

The Sagnac interferometer has been used to support fiber optic gyros to sense rotation which currently represents the largest single market for fiber sensors. The Sagnac fiber optic interferometer may also be used to sense time varying and very slowly varying environmental effects as well as instrumentation to measure the properties of light sources and optical fiber. This paper provides an overview of these and other applications of the Sagnac fiber optic interferometer.
