Sagnac sensor for location of a disturbance

Sagnac sensor for location of a disturbance

A sensor is investigated that uses the positional dependence of the sensitivity of a Sagnac loop to determine the position of a disturbance. Error contributions from optical sources and distributed acoustical noise sources are discussed, and methods for optimizing the nonlinear time-averaged positio...

Zusammenfassung:A sensor is investigated that uses the positional dependence of the sensitivity of a Sagnac loop to determine the position of a disturbance. Error contributions from optical sources and distributed acoustical noise sources are discussed, and methods for optimizing the nonlinear time-averaged position estimator are presented. An experimental version of the sensor is investigated with realistic disturbances.
