Method and assembly for an interferometric fiber optic gyro

A method for determining an accurate phase difference between a phase of a light beam in each of two light paths, the two light paths being in a rotating interferometric fiber optic gyro, by measuring a first phase difference due to angular velocity of the rotating interferometric fiber optic gyro,...

Zusammenfassung:A method for determining an accurate phase difference between a phase of a light beam in each of two light paths, the two light paths being in a rotating interferometric fiber optic gyro, by measuring a first phase difference due to angular velocity of the rotating interferometric fiber optic gyro, flipping axes of rotation of photons in the light loops of the rotating interferometric fiber optic gyro, and measuring a second phase difference due to angular velocity of the rotating interferometric fiber optic gyro.
